Salts:
Salts are ionic compounds formed by the neutralization reaction between an acid and a base. They consist of a positive ion (cation) from the base and a negative ion (anion) from the acid.
Examples:
1. Sodium chloride (NaCl) – Used as table salt.
2. Calcium carbonate (CaCO₃) – Found in limestone and used in cement manufacturing.
3. Potassium nitrate (KNO₃) – Used in fertilizers and explosives.
Properties of Salts:
1. State: Salts are usually crystalline solids.
2. Solubility: Most salts dissolve in water, but some (e.g., barium sulfate) are insoluble.
3. Electrical Conductivity: Aqueous solutions of salts conduct electricity.
4. Reaction with Water: Some salts undergo hydrolysis, reacting with water to form acidic or basic solutions.
