Answer: He could add a base to the pool to neutralize the acid.
Explanation:
Chlorine is used to disinfect the pools as it produces hypochlorous acid in water. This hypochlorous acid is unstable and gives hydrochloric acid and nascent oxygen which is used to disinfect.
The excess acid is neutralized by adding base which produces salt and water and thus decrease the acidity.
Adding more acid would increase the acidity further.
The mass of KCl that exists in 20.3 g of solution containing 1.14% by mass of KCl is 0.23 g
From the question given above, the following data were obtained:
Mass of solution = 20.3 g
Percentage of KCl = 1.14% = 1.14 / 100 = 0.0114
<h3>Mass of KCl =?</h3>Cross multiply
Mass of KCl = 0.0114 × 20.3
<h3>Mass of KCl = 0.23 g</h3>Therefore, the mass of KCl in the solution is 0.23 g
