Conner is testing the pH of a swimming pool and he finds it to be 6.5. Optimal pH for swimming is between 7.0 and 7.6. Conner adds a compound to the pool and waits a few hours. He retests the pool water and finds the pH to be 7.2.
What did Conner do to raise the pH of the pool?
A) He added water to raise the pH.
B) He added a base to raise the pH.
C) He added a salt to raise the pH.
D) He added an acid to raise the pH.

Answer : The correct option is, KCl is the salt and KOH is the base.

Explanation :

Neutralization reaction : It is a type of reaction in which an acid react with a base to give a salt and water as a product.

The balanced chemical reaction is :

The given balanced reaction is an example of neutralization reaction in which KOH is a base and HCl is an acid when both combine the it gives KCl as a salt and as a water.

Hence, the correct option is, KCl is the salt and KOH is the base.
