Answer

Brief Explanations:

The pH scale is logarithmic. A decrease of one unit on the pH scale means the hydrogen - ion concentration ($[H^+]$) increases by a factor of 10. For example, if pH changes from 3 to 2, and since $pH=-\log[H^+]$, when $pH = 3$, $[H^+]=10^{-3}$ M, and when $pH = 2$, $[H^+]=10^{-2}$ M, which is a ten - fold increase.

Answer:

tenfold increase in
