For a certain solution, the concentration of hydronium ions is greater than the concentration of hydroxide ions. Therefore, the pH of the solution ___________.

Question

a) must be greater than 7.
b) must be less than 7
c) must be exactly 7
d) can either be less than or greater 7, but not equal to 7
e) cannot be predicted in reference to pH 7

Answer 1

b) must be less than 7

Answer 2

are you sure

Answer 3

I apologize for any confusion. I made an error in my previous response.

If the concentration of hydronium ions is greater than the concentration of hydroxide ions, it means that the solution is acidic. In an acidic solution, the pH is less than 7. Therefore, the correct answer is:

b) must be less than 7
