(i) When silver nitrate solution is added to sodium chloride solution, a white precipitate of silver chloride is formed along with sodium nitrate solution. AgNO3(aq)+ NaCl(aq) --------> AgCl(s) + NaNO3(aq)      ...

It is because of the products formed: chlor for chlorine and alkali for sodium hydroxide.

The correct answer is (D) white

(C) carbon dioxide only

When barium chloride solution and sodium sulphate solution are mixed together, an insoluble salt is formed, which is barium sulphate, and white in colour. BaCl2(aq) + Na2SO4(aq) → BaSO4(s) ↓ +...
