Question

Rahul has three bottles one containing hydrochloric acid, another sodium hydroxide and third suger solution how he will identity them if he has china Rose solution with him

Answer 1

Since china rose solution is a natural indicator of acid an base so china rose solution gives dark pink (magenta) colour with acid and green colour with base.

Hydrochloric acid is acid so when it will react with china rose solution give magenta colour..

Sodium hydroxide is a base so it will give green colour with china rose solution..

Lastly sugar solution is neutral hence it will appear colourless...
