This document discusses acids and bases, including their properties and how to test for them. It provides information on:
- The pH scale ranges from 0-14, with acids having lower values and bases having higher values. A pH of 7 is neutral.
- Acids donate H+ ions in solution and have a pH below 7. Bases donate OH- ions and have a pH above 7.
- Indicators like litmus paper and cabbage juice can be used to test if a substance is acidic or basic - acids turn indicators one color while bases turn them another.

Acids have sour tastes and are corrosive. Common acids include citric acid in lemon juice and ethanoic acid in vinegar. Strong acids like hydrochloric, sulfuric, and nitric acids are dangerous because they can absorb water and cause burns or react violently with skin. Alkalis are also corrosive and slippery. When acids and alkalis neutralize each other in a chemical reaction, they form salts and water. Indicators change color in acids and alkalis and are used to test whether a solution is acidic or basic. Litmus turns red in acids and blue in bases. Universal indicator shows the strength of acidity or alkalinity through different colors.

The document discusses the meaning, significance, and application of Hazard and Operability (HAZOP) and Hazard Identification (HAZID) studies for oil and gas engineering, procurement, and construction (EPC) pipeline and process facilities projects. It explains that HAZOP and HAZID studies identify hazards in a system and possible incidents in order to reduce risks. They provide a systematic assessment of hazards and result in improved systems, procedures, and safety awareness. The studies are most beneficial when conducted early in the design process or on existing facilities.

An acid is a solution that has excess hydrogen (H+) ions, giving it sour properties. The more H+ ions present, the more acidic the solution. Acids can taste sour, conduct electricity, corrode substances like skin and paper, and turn litmus paper red. Common acids include acetic acid in vinegar and citric acid in citrus fruits. Acidic solutions have a pH below 7. Bases are solutions with excess hydroxide (OH-) ions that feel slippery and taste bitter. They turn litmus paper blue. Common bases are found in soaps, ammonia, and cleaning products. When acids and bases are mixed, a neutralization reaction occurs.

substances. Many
acids can corrode
fabric, skin ,and
4. Uses of Acids

production of
fertilizers, steel, paints, and
plastics.

8. pH Scale
• pH is a measure of how acidic or basic a solution is.
• The pH scale ranges from 0 to 14.
•
•
•
•
Acidic solutions have pH values below 7
A solution with a pH of 0 is very acidic.
