chlorine makes a pool slightly basic. if the (H+) concentration of the pool is 8.1 x 10 to the power of -11. what is the pH of the pool?

Answer 1

Hello, Lexi,

pH is defined as the negative log of the H⁺ concentration.

[H⁺] in this case is 8.1x10^-11.

The log of 8.1x10^-11 is -10.1. The negative of that is 10.1, rounded to 10, since we only have 2 sig figs.
