_____________________________

4. A black substance precipitate of copper sulphate is formed and sulphur dioxide gas is also form left in the solution. ___________________________

5. Barium sulphate is formed which is a white powder precipitate. And sodium chloride left in the solution. ____________________________

6. When calcium Oxide added to water. It is highly exothermic process. And calcium hydroxide will form and heat also form

________________________________

7.silver chloride precipitate will form. It is white in colour.
