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...
