The formula for determining the pH of a solution is pH = -log[H+], where [H+] is the hydrogen ion concentration (in M/L). What is the hydrogen ion concentration of an acid with a pH of 2.5?

-2.5 = log H+

10^-2.5 = H+ = .00316

By the way I do not understand the notation used in your other problem.

To find the hydrogen ion concentration ([H+]) of an acid with a pH of 2.5, we can use the formula pH = -log[H+].

First, rearrange the formula to solve for [H+]: [H+] = 10^(-pH).

Now substitute the given pH value into the formula: [H+] = 10^(-2.5).

To evaluate this, remember that raising 10 to a negative power is the same as taking the reciprocal of 10 raised to the positive power: [H+] = 1 / 10^2.5.

Calculating this expression, [H+] is approximately 0.00316 M/L, or 3.16 x 10^(-3) M/L.

Therefore, the hydrogen ion concentration of the acid with a pH of 2.5 is approximately 3.16 x 10^(-3) M/L.
