Question

State your observation for the following.(Equations not required.
i. When a solution of silver nitrate is added to a solution of silver chloride.
ii. When copper carbonate is heated.​

Answer 1

i) When a few drops of a silver nitrate solution are added to a slightly acidic aqueous solution that contains chloride ions, a white precipitate of silver chloride will form.

ii) If a copper carbonate is heated with carbon, a chemical reaction takes place. Initially the copper carbonate thermally decomposes into copper oxide. Then the carbon reacts with the copper oxide liberating pure metal in a type of displacement reaction.
