Equal volumes of hydrochloric acid and potassium hydroxide solutions of same concentration are mixed and the pH of the resulting solution is analysed with pH strip.

What is the colour obtained in the reacting mentioned in above passage?

A

Yellow

B

Red

C

Yellowish green

D

Blue

Text Solution

Verified by Experts

The correct Answer is:
C
Explanation: When strong base (KOH) and strong acid (HCl) reacts, neutral salt is form. The universal indicator colour Guide shows that Universal Indicator turns red when it is addd to a strong acid, it turns purple when it is added to a strong base, and it turns a yellowish green when it is added to a neutral solution.
