If the [H+] of a drain cleaner solution  is 1 × 10-4 M, the pH of the drain cleaner solution is________, and the drain cleaner solution  is ______.Group of answer choices 8; acidic    4; acidic14; basic   4; basic7; neutral

The pH of a solution is calculated using the formula pH = -log[H+]. In this case, the [H+] of the drain cleaner solution is given as 1 × 10^-4 M.

Step 1: Substitute the given [H+] into the formula. pH = -log(1 × 10^-4)

Step 2: Calculate the pH. pH = 4

Therefore, the pH of the drain cleaner solution is 4.

The pH scale ranges from 0 to 14. A pH less than 7 is considered acidic, a pH greater than 7 is considered basic, and a pH of 7 is considered neutral.

Since the pH of the drain cleaner solution is 4, which is less than 7, the drain cleaner solution is acidic.

So, the answer is "4; acidic".
