Which of the following is true of a substance with a pH of 11.0?
A. The substance is an acid.
B. The substance is a base.
C. The substance is neutral.
D. The substance is a transition metal.
I think A
pH
<7 = acid
= 7 = neutral
>7 = base
Just for anyone seeing this question now, the answer is B. A pH scale goes from 0 (acidic) to 14 (base)
To determine which statement is true of a substance with a pH of 11.0, we need to understand what pH represents. pH is a measure of the acidity or alkalinity of a substance and ranges from 0 to 14. A pH of 7 is considered neutral, values below 7 indicate acidity, and values above 7 indicate alkalinity or basicity.
In this case, a substance with a pH of 11.0 falls into the alkaline or basic range. Therefore, statement B, "The substance is a base," is correct.
