Question

how would you distinguish between dilute HCL and dilute HNO3 by addition of one solution only

Answer 1

By adding, a few drops of AgNO3

Dil. HCl reacts with silver nitrate to give a white ppt. of silver chloride.

On the other hand there is no reaction observed when dil. Nitric acid is treated with silver nitrate solution. That is obvious thing.

Reactions :-

HCl(aq) + AgNO3(aq) >>> AgCl(s) + HNO3(aq)

HNO3(aq) + AgNO3(aq) >>> No reaction + No ppt.

Answer 2

Answer:

Add a few drops of AgNO3 solution to dil. HCl and dil. HNO3 acid we get that dil HCl reacts with silver nitrate to give a white ppt. of AgCl on the other hand there's no reaction observed when dil. HNO3 is treated with silver nitrate solution.

Reactions are given below:-

HCl (aq) + AgNO3 (aq) ---------> AgCl (s) + HNO3 (aq)

HNO3 + AgNO3 ---------> no reaction and no ppt.

Hope this helps you
