Answer:

A solution with a pH of 2 is 100 times acidic as a solution of pH 4

Explanation:

pH=2
Then, #-logH3O^+=-log10^-2#
Concentration of #H3O^+# = #10^-2#
When pH =4
concentration of #H3O^+ = 10^-4#
Therefore, #10^-2/10^-4=10^2=100#
A solution with a pH of 2 is 100 times acidic as a solution of pH 4
