Two test tubes 'A' and 'B' are given.Test tube 'A' contains blue litmus solution and test tube 'B' contains red litmus solution.A solution with PH 2 is added in both the test tubes .In which of the two would you observe a colour change.....

We will observe a change in test tube a as ph 2 is highly acidic which turns blue litmus red

Hey dear,
● Answer -
Test tube A will show color change from blue to red due to acid.
● Explaination -
pH is a logarithmic scale used to specify the acidity or basicity of an aqueous solution.
According to pH,
pH < 7 => acidic => turn litmus soln red
pH = 7 => neutral => no change in colour
pH > 7 => basic => turn litmus soln blue
Given solution having pH 2 must be acidic and will turn blue litmus soln to red.
Hence, we'll observe color change (blue to red) in test tube A.
Hope this helps you...
