MrMuchimi

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.

Cl_2+H_2O\rightarrow HOCl

HOCl\rightarrow HCl+O

The excess acid is neutralized by adding base which produces salt and water and thus decrease the acidity.

Acid+Base\rightarrow Salt+water

Adding more acid would increase the acidity further.

Which of the following statements is true regarding scientific hypotheses?
attashe74 [19]

I would say D.  

A is incorrect by simple reasoning.

B is also incorrect. A hypothesis is made before evidence supports it, therefore, it doesn't matter if all evidence supports it,  as it shows an guess. It sometimes can also lead to more experimentation even if it's not true for the current experiment.

C is also incorrect. An untestable hypothesis isn't useful as you cannot test anything relating to it, and it cannot be proven or disproven.

Hope this helps!
