Answer:
Basic
Explanation:
The pH of a substance is a measure of the acidity of a substance.
The pH of a substance is calculated using the formula:
[tex]pH = -log [H_3O^+][/tex]
where
[tex][H_3O^+][/tex] is the concentration of hydronium ion in the solution
A substance is classified as follows depending on the value of its pH:
- pH between 0 and 7: acidic solution
- pH of 7: neutral solution
- pH between 7 and 14: basic solution
So in this problem, since the pH of the liquid drain cleaner is 13.5 (between 7 and 14), the substance is strongly basic.
