Question

A student added red litmus solution to A and observed that it
changed into blue When she added another solution B to A in excess
she observed that solution turned red THe solution Aand B is
a) KOH and KCL b) HCL and KOH c) KOH and HCL d) HCL and
H2CO3

Elisha Kumari · Accepted Answer

Solution A is base as bases turn red litmus solution into blue
Solution B is HCl as acids turns blue litmus solution into red
Therefore, the correct option is (C) as KOH and HCl are base and
acid respectively

A student added red litmus solution to A and observed that it changed into blue. When she added another solution B to A in excess she observed that solution turned red.THe solution Aand B is a) KOH and KCL b) HCL and KOH c) KOH and HCL d) HCL and H2CO3
