Question

What are the physical and chemical properties of common salt?

Answer 1

Salt, substance produced by the reaction of an acid with a base. A salt consists of the positive ion of a base and the negative ion of an acid. The main kind of salt is sodium chloride with the chemical formula $NaCl$ . Salts can be classified in a variety of ways. Salts that produce hydroxide ions when dissolved in water are called alkali salts.

Complete answer:
Physical properties of salt:
Solid salts tend to be transparent as illustrated by sodium chloride. In many cases, the apparent opacity or transparency are only related to the difference in size of the individual monocrystals. Since light reflects from the grain boundaries, larger crystals tend to be transparent, while the polycrystalline aggregates look like white powders. Salts of strong acids and strong bases are non-volatile and often odorless, whereas salts of either weak acids or weak bases may smell like the conjugate acid salts are characteristically insulators. And Salts characteristically have high melting points.
Chemical properties of salt:
Sodium chloride is a readily soluble compound in water and other polar solvents and is a stable solid. It decomposes only at high temperatures to produce toxic fumes of disodium oxide and hydrochloric acid.
Oxidation: Combines with oxygen at room temperature.
Flammability: Burns with a brilliant golden-yellow flame.

Note:
Strong salts or strong electrolyte salts are chemical salts composed of strong electrolytes. These ionic compounds dissociate completely in water. They are generally odorless and nonvolatile. Weak salts or weak electrolyte salts are, as the name suggests, composed of weak electrolytes. They are generally more volatile than strong salts. They may be similar in odor to the acid or base they are derived from.
