Question

The hydrogen ion concentration of tomato juice (pH 4) is how many times higher than the hydrogen ion concentration of 0.01 M NaOH (pH 12)?​

Answer 1

Answer:

Explanation:

Peter Johnston’s answer is correct but a bit terse. So, let’s go to the definition of pH. pH is defined as

pH = -log[H+}

-pH = log[H+]

10^(-pH) = [H+]

so, given a pH of 2.4

10^-2.4 = [H+]

0.00398 = [H+]
