2. Potassium nitrate: It is made from potassium hydroxide and nitric acid.

It is soluble in water. Its solution in water is neutral as it made up by the reaction between a strong acid and a strong base.

3. Aluminium chloride: It is made from aluminum hydroxide and hydrochloric acid. It is soluble in water. Its solution in water is slightly acidic as it is made up by the reaction between a strong acid and a weak base.

4. Copper sulphate: It is made from copper hydroxide and sulphuric acid. It is soluble in water. Its solution in water is slightly acidic as it is made up by the reaction between strong acid and weak base.

5. Sodium acetate: Sodium acetate is made from sodium hydroxide and acetic acid. Sodium acetate is soluble in water. Sodium acetate is basic in nature as it is made up by the reaction between a strong base and a weak acid.

6. Sodium carbonate: Sodium carbonate is made up from sodium hydroxide and carbonic acid. Sodium carbonate is soluble in water. Sodium carbonate is basic in nature as it is formed by the reaction between a strong base and a acid.

7. Sodium hydrogen carbonate: Sodium hydrogen carbonate is made up from sodium hydroxide and carbonic acid. Sodium hydrogen carbonate is sparingly soluble in water. It is basic in nature as it is formed by the reaction between a strong base and a weak acid.

8. Common salt: Common salt or table salt is sodium chloride. It is used in the production of many substances like sodium hydroxide, baking soda. washing bleaching powder. A solution of salt in water in called brine.
