The pH can be calculated using the equation pH = –log(H+), where H+ is the hydronium ion concentration. Find the hydronium ion concentration of a particular lemon juice if the pH level is 2.1.

pH = – log(H+)

If 2.1 = – log(H+), then

    -2.1 = log(H+), and so

    10^(-2.1) = H+

We do that last step using the fact that log(x) and 10^x are inverse functions.
