Nik hypothesized that zinc would dissolve most in vinegar because zinc is the softest metal and vinegar is the most acidic liquid. After testing zinc, silver, brass, and a quarter in vinegar, baking soda, Coke, and saltwater for 5 and 10 days, Nik found that zinc completely dissolved in vinegar, turning pink. Vinegar also corroded the other metals, though not as much as zinc. This supported that vinegar is the most acidic and corrodes metals the most.

What metal will dissolve first
The document describes an experiment where zinc, silver, brass, and a quarter were submerged in vinegar, baking soda, Coca-Cola, and saltwater for 10 days. By the end of the experiment, all of the metals had completely lost their original color and texture, becoming softer and less noisy when dropped. The zinc submerged in vinegar turned pink, and overall the liquids were very effective at corroding the different metals over the course of the experiment.
What metal will dissolve first
The document describes an experiment where different metals (zinc, silver, brass, and a quarter) were submerged in various liquids (vinegar, baking soda, Coke, and saltwater) for 5 and 10 days. After 10 days, all the metals had changed color and become softer, making less noise when dropped on the ground. The zinc submerged in vinegar turned pink. Overall, the liquids were quite effective at corroding the different metals over time.

Which Metal Will Dissolve First?
Nik hypothesized that zinc would dissolve the most in vinegar because zinc is the softest metal and vinegar is the most acidic liquid. After testing zinc, silver, brass, and a quarter in vinegar, baking soda, Coke, and saltwater for 5 and 10 days, Nik found that zinc dissolved the most in vinegar, turning pink and reducing in size. Vinegar also corroded the other metals, while saltwater corroded them but not as much as vinegar. Baking soda and Coke had little effect. The experiment proved that vinegar is the most acidic and corrodes metals the most.
Metals: Physical Properties
Metals generally exist in the solid state and have a shining surface or luster. However, some metals like mercury are liquid at room temperature, and gallium melts at 30 degrees Celsius. Most metals are hard, but sodium, potassium, rubidium, cesium, mercury, gallium and zinc are soft. Metals can be beaten into thin sheets because they are malleable, and drawn into thin wires because they are ductile, with gold and silver being the most malleable and ductile. Mercury, sodium, potassium and zinc are exceptions as they are not very malleable or ductile.
Corrosion and its Preventive Measures
Method-1. Barrier Protection. Corrosion of iron, or rusting, can be prevented by galvanization, which is coating iron with zinc. Zinc does not corrode and forms a protective coating on the iron.
Method-2. Galvanization. Rusting can also be prevented by coating iron with chromium, tin, nickel or aluminum through electroplating. These metals resist corrosion and protect the iron.
Method-3. Alloying. Corrosion can be prevented by alloying iron with chromium and nickel to form stainless steel, which does not corrode easily.
Non Metal, Physical Properties
Non-metals exist in solid and gaseous states like nitrogen, oxygen and carbon. They lack luster except for diamond and graphite. Non-metals are soft but diamond is the hardest natural substance. Non-metals are brittle and cannot be hammered or stretched like metals because they have low tensile strength.

Ediblepackaging
This document discusses edible packaging as an environmentally friendly alternative to traditional plastic packaging. It provides an introduction to edible packaging, explaining why it is needed due to the large amount of non-biodegradable plastic waste. Edible packaging is defined as a thin edible coating or film that can be consumed as part of the food. Various biopolymers like proteins, polysaccharides, and lipids can be used to form these edible coatings and films. While edible packaging has benefits like reducing waste and adding nutrition, it also faces challenges for wide commercial use like high costs and poor barrier properties compared to plastic.

What metal will dissolve first
The document describes an experiment testing which metal would dissolve fastest in different liquids. The hypothesis was that zinc would dissolve most in vinegar due to zinc being the softest metal and vinegar being the most acidic liquid. After 5 and 10 days, zinc had dissolved the most in vinegar, turning pink and reducing in size. Vinegar also corroded the other metals, while saltwater corroded them but not as much as vinegar. Baking soda and Coke had little effect. The experiment proved vinegar is the most acidic and corrodes metals the most.

Zinc (Zak Konys)
Zinc is a bluish-white metal that is found naturally in the Earth's crust. It was likely first discovered and purified in ancient China around 1000 AD, and was later described as a metal by the Swiss alchemist Paracelsus in the 15th century. Zinc is commonly used today to galvanize other metals and prevent corrosion, as well as in the production of many compounds for applications like rubber, paint pigment, animal feed supplements, and more. The largest producers of zinc today are China, Australia, Peru, the United States, and Canada.
Metal relationship
The document discusses the relationship between a metal's reactivity and when it was discovered. It analyzes metals discovered at different points in history and finds that generally, less reactive metals like gold were discovered earlier since they occur freely in nature, while more reactive metals discovered later once technology advanced to extract them from ores. There is not always a direct correlation, as in the case of copper being discovered before silver, but the pattern typically holds except over very short periods. The conclusion is that less reactive metals were discovered earlier due to being more easily accessible.
Chapter 4 metals and non-metals
This document discusses the properties and reactions of metals and non-metals. It includes several activities to classify different materials as metals or non-metals based on their properties like conductivity and malleability. The document also describes displacement reactions between metals and explains that more reactive metals can displace less reactive ones from their compounds in water. Common uses of metals and non-metals are also outlined.
Chemistry experiment
The student conducted an experiment to see how different metals affect the rusting of iron nails. They placed iron nails wrapped in copper or zinc ribbons, coated in vaseline, or unwrapped into test tubes of water. After 4 days, the nail with copper rusted heavily, the nail with zinc and vaseline-coated nail did not rust, while the bare nail rusted heavily. The student concluded that copper does not prevent rusting, while zinc will rust instead of iron, protecting the nail from corrosion.

2009 rocks_and_minerals__the_restless_earth_
René-Just Haüy accidentally dropped a crystal of calcite at a friend's house in 1779. When it shattered, he noticed that each piece broke into a perfect cube shape. This led him to systematically smash and study how other crystals broke. He discovered that crystals break along smooth planes called cleavage planes, which reveal the internal structure of how the mineral's molecules are stacked. His work showed that the internal structure determines a mineral's external shape and how it will break, allowing scientists to distinguish different minerals based on their cleavage. Haüy is now considered the founder of crystallography, the study of crystal structures.
2009 rocks_and_minerals__the_restless_earth_
This document provides an overview of rocks and minerals. It explains that rocks are made up of smaller pieces called minerals, which are natural solid materials composed of specific molecules stacked together in an orderly structure. Minerals form in different ways, including through volcanic activity when magma cools, through burial deep underground where pressure causes metamorphism, and through interactions with water. Understanding the composition and structure of minerals provides clues about how rocks form and what geological processes they have undergone.
Patterns Of Reactivity
The document discusses the reactivity and extraction of various metals. It introduces the reactivity series, which ranks metals based on their reactivity with oxygen, acids, and water. More reactive metals are higher in the series and displace less reactive ones. Extraction methods depend on reactivity - less reactive metals like copper can be extracted by heating their ores with carbon, while very reactive metals require electrolysis.

What metal will dissolve first?
- 1. Which Metal Will Dissolve First? Nik
- 2. Hypothesis I believe, based on my research, that zinc will be corroded the most by vinegar because zinc is the softest of the metals and vinegar is the most acidic of the liquids.
- 3. I will be testing these metals.
- 4. Metals in liquids after 5 days
- 5. Metals in liquids after 10 days This column displays the effects of vinegar on zinc, silver, brass, and a quarter. This column displays the effects of baking soda on is zinc, silver, brass, and a quarter.
- 6. Metals in liquids after 10 days This column displays the effects of Coke on zinc, brass, silver, and a quarter. This column displays the effects of saltwater on zinc, brass, silver, and a quarter.
- 7. I was right about the zinc in vinegar. The zinc turned this pinkish color and was smaller than all the other zinc. Vinegar also corroded all the other metals in vinegar. They weren't as soft, but they were corroded. This proves vinegar is the most acidic and corrodes the metals the most.
- 8. Conclusion After 10 days all the metals have completely lost their original color. They have also become softer. When I dropped them, they didn’t make as loud of a noise when they hit the ground like they did before I put them in the liquids. The zinc in the vinegar I thought was strange because it turned this pinkish color. Liquids caused corrosion of all the metals.
