An aqueous solution of potassium hydroxide is standardized by titration with a 0.194 m solution of hydrobromic acid. if 25.2 ml of base are required to neutralize 24.2 ml of the acid, what is the molarity of the potassium hydroxide solution? m potassium hydroxide

The molarity of potassium hydroxide is 0.186 M

Explanation:

To calculate the molarity of base, we use the equation given by neutralization reaction:

where,

are the n-factor, molarity and volume of acid which is HBr

are the n-factor, molarity and volume of base which is KOH.

We are given:

Putting values in above equation, we get:

Hence, the concentration of potassium hydroxide is 0.186 M.
