Question

Rahul, Esha and their friend Deepak
were provided with a test tube each
containing China rose solution which
was pink in colour. Rahul added two
drops of solution 'A' in his test tube
and got a dark pink colour. Esha
added 2 drops of solution 'B' to her
test tube and got green colour.
Deepak added 2 drops of solution 'C'
but could not get any change in
colour. Identify the nature of
solutions A, B and C.​

Answer 1

Answer:

China rose is a natural indicator which changes acid to pink colour, base to green colour and neutral solutions do not show any changes.

So, the solution A is an acid, B is a base and C is neutral.
