What is the H+ of a solution with a pH of 5.0? use a scientific calculator

1.0 x 10^-5M

Explanation:

The pH of a solution is the concentration of hydrogen ion concentration in the solution. Mathematically, it is expressed as pH = -log(H+), where H+ is the concentration of hydrogen ion

So, for the slightly acidic solution with pH 5.0

5.0 = -log(H+)

(H+) = Antilog (-5.0)

(H+) = 0.00001M

Place (H+) in standard form

(H+) = 1.0 x 10^-5M

Thus, the concentration of hydrogen ion in the solution with pH 5.0 is 1.0 x 10^-5M
