This document discusses concentration in the context of making soft drink solutions. It explains that concentration refers to the amount of material dissolved in a given volume of liquid, with more dissolved material resulting in a more concentrated solution. The document asks questions about determining if a soft drink is a mixture or solution, how to test if it is a solution, how to identify a saturated solution, and what happens to the concentration when more powder is added to a fixed volume of water.

Investigation 3 revised
This document discusses concentration in solutions. It describes how concentration refers to the amount of material dissolved in a given volume of liquid, with more concentrated solutions having more material dissolved. It discusses making concentrated and dilute soft drink solutions by varying the amount of powder mixed in water. It also describes investigating the concentration of salt solutions and developing procedures to determine which of three mystery solutions has the different concentrations without tasting them.
Investigation 3
The document discusses an investigation into the concentration of soft drink solutions. It describes mixing different amounts of soft drink powder with 1000ml of water to create solutions, then comparing the solutions' appearance, taste, and concentration. When more powder is dissolved in a given volume of water, the solution is more concentrated and tastes sweeter. The goal is to determine the best amount of powder to use to make a good tasting drink.
Talking about colour ppt
This document provides adjectives to describe colours, listing light, bright, vivid, and glowing colours as well as dark, subdued, and gloomy colours. It also notes that contrasting colours stand out next to each other while complimenting colours blend into each other.
Mixtures and solutions
A mixture is when two or more substances are combined but can be separated, while a solution is when substances are mixed together and cannot be separated. Examples given include cereal and milk being a mixture that can be separated, while lemonade is a solution because the ingredients cannot be separated once mixed.
what is saturated,unsaturated and supersaturated solution
The document defines key terms related to solutions. A solute is the substance that dissolves in a solvent, the liquid in which the solute dissolves. An unsaturated solution contains less than the maximum amount of solute that can dissolve, a saturated solution contains the maximum amount of solute, and a supersaturated solution temporarily contains more solute than a saturated solution by forcing excess solute into the liquid.
Concentration2008
The document compares saturated, unsaturated, and supersaturated solutions. It defines concentration and discusses calculating concentration by mass and volume. It also discusses factors that increase the rate of dissolving, such as heating and stirring, and provides examples of different types of solutions.
2 types of solutions
The document discusses different types of solutions. It states that in the solution of Kool-aid, the solute is Kool-aid and the solvent is water. It defines concentrated solutions as having more solute and less solvent, diluted solutions as having less solute and more solvent, and saturated solutions as having the solute equal the amount of solvent and reaching the point of solubility at a given temperature.
Solutions
The document discusses solutions and mixtures. A solution is formed when a solute dissolves in a solvent, usually water, forming a clear, homogeneous liquid. The total mass of a solution equals the mass of the solvent plus the solute. Solutions can be separated using methods like filtration, evaporation, and distillation. Mixtures that contain undissolved solids or multiple liquids can also be separated using these and other techniques like chromatography.

Q1 week 2- SOLUTIONS
Solubility is affected by temperature, particle size, and stirring. Usually, increasing the temperature increases solubility as it provides more energy for particles to separate. Finer particles dissolve faster than larger ones because they have a greater surface area exposed to the solvent. Stirring improves solubility by reducing concentration gradients that inhibit dissolving. Other factors like amount of solvent, nature of solute and solvent, and immiscibility also influence solubility rates. Experiments showed that salt, sugar, and detergent dissolved faster with increased temperature, finer particles, and stirring.
MIXTURES(APPEARANCE AND USES)
This document describes experiments on solubility conducted over 4 days:
- Students observed how various solids like sugar, salt, and detergent dissolved in water. Temperature, particle size, and stirring affected solubility. Finer particles and higher temperatures increased dissolution rates.
- Solutions were defined as homogeneous mixtures where a solute fully dissolves in a solvent, like sugar in water. Factors like amount of solvent and manner of stirring impacted solubility.
- Through experiments, it was shown that increased temperature, finer particle size, and stirring facilitated faster dissolution of solutes like sugar and salt in water. The nature of the solute and amount of solvent also determined dissolution rates.
7 Science Chapter 8.ppt
This document provides an overview of solutions and factors that affect the dissolving process. It defines a solution as a homogeneous mixture that appears as a single substance. Solutions are made up of a solute, the substance that dissolves, and a solvent, the substance the solute dissolves in. The rate at which a solute dissolves, or its solubility, depends on properties like temperature, pressure, the size of solute particles, and stirring. Higher temperatures typically increase solubility for solids but decrease it for gases. Smaller solute particles and higher pressures also increase solubility.
Mixtures
The document discusses different types of mixtures including solutions, suspensions, and colloids. It explains that a solution is a homogeneous mixture of two or more substances where a solute dissolves evenly throughout a solvent. Suspensions are heterogeneous mixtures where insoluble particles settle out of the mixture. Colloids have intermediate particle sizes that do not settle out.
Mixtures And Solutions Lesson 1
A mixture is a combination of two or more substances that retain their individual chemical and physical properties. There are two types of mixtures: homogeneous mixtures, where the substances are evenly mixed on a small scale and cannot be seen, and heterogeneous mixtures, where the individual substances can be visually identified. A solution is a type of homogeneous mixture where one substance dissolves evenly into another, such as sugar dissolving in water, forming a mixture on a molecular scale. Not all mixtures are solutions, as solubility determines whether a substance will dissolve in another.

Ppoint Solutions&Mixtures
A mixture is composed of two or more substances that are not chemically combined. There are two types of mixtures - heterogeneous mixtures where the phases can be seen, and homogeneous mixtures where the phases cannot be seen. A solution is a special type of homogeneous mixture containing a solute dissolved in a solvent. The solute is the part that dissolves, like salt or sugar, while the solvent does the dissolving and is usually a liquid like water. The concentration of a solution depends on how much solute is added, with dilute solutions having little solute and concentrated solutions having a large amount. A saturated solution contains as much solute as it can dissolve under given conditions, while a supersaturated solution contains more solute than
