acids, bases, and the pH scale

Controls

pH measures hydrogen-ion concentration on a logarithmic scale. Each unit is a 10× change — pH 3 is ten times more acidic than pH 4.

pH3.00

pOH11.00

[H⁺]1.0e-3

[OH⁻]1.0e-11

Governing equation

pH = - lo g_{10} [H^{+}] = - lo g_{10} (1.0 e - 3) = 3.00

Reading this result: Acidic: [H⁺] of 1.0e-3 M outnumbers OH⁻, and because pH + pOH always sums to 14, the pOH here is 11.0.
