Question

Determine how many times more acidic a solution is at pH 2 relative to pH 8.0. Enter your answer and please explain steps.

Answer 1

Since the pH scale is logarithmic, when you increase between any pH to the next pH on the scale it increases 10x.

Between pH 2 and pH 8 there is a 10^6 difference. Therefore, pH2 is 10^6 more acidic than pH 8.
