Question

There are two solutions A and B.Solution A turns red litmus blue whereas solution B turns blue litmus red.Both the solutions are mixed to give a new solution C.C will change:

• A. blue litmus red
• B. red litmus blue
• C. no change in colour
• D. may be A or B

Answer 1

The correct option is D may be A or B

$A$ is basic. $B$ is acidic.

$A+B$ is basic if $A$ is strongly basic and $B$ is weak acid.

$A+B$ is acidic if $A$ is weak base and $B$ is strong acid.

So, both are possible.
