The pH of a solution is 2.0. Which statement is correct?

Useful formulas include [H30+1 = 1070F, FOH-7-10 + 0H, PH+pOH = 14, and [H30 [0H-] - 10-14

pH + pOH = 14, [H₃0⁺] [0H⁻] = 10⁻¹⁴

Explanation:

When it comes to questions involving pH, the equations used are;

[H₃0⁺] [0H⁻] = 10⁻¹⁴

This equation shows the concentration of hydroxonium ions alongside that of the hydroxide ions.

pH + pOH = 14

If the value of either the pH of the pOH is know, one can calculate the value of the other using this equation.
