Study Notes
Acids and Bases
- All acids have the common property of donating a proton (H+ ion).
- Turmeric is a natural indicator, and it changes color in the presence of acids or bases.
Reaction between Acids and Bases
- When a base reacts with a metal, it produces hydrogen gas.
- The reaction between an acid and a base forms a salt and water.
Properties of Bases
- Bases are distinguished from acids by their ability to accept a proton (H+ ion).
Salt Formation
- When a weak acid reacts with a strong base, a basic salt is produced.
Dissolving Acids and Bases
- The exothermic nature of dissolving acids or bases in water is due to the release of heat energy during the process.
Acids in Water
- Acids produce H+ ions when dissolved in water.
pH Scale
- The pH scale is a logarithmic scale that measures the concentration of H+ ions in a solution.
- A pH range of 7-8 accurately represents the pH scale.
Human Body and pH
- The human body normally functions within a pH range of 7.35-7.45.
Applications of Chemicals
- Sodium hypochlorite is commonly used in the textile industry for bleaching cotton and linen.
- Plaster of Paris (calcium sulfate hemihydrate) is a compound used by doctors for supporting fractured bones.
