Tutorial to help answer the questionWhat is the pH of a 10 - 3 M solution of HCl?
Tutorial
Calculating pH from [H +] ConcentrationpH is the negative log of the hydrogen ion concentration, i.e. pH = -log [H +] HCl is a strong acid. It completely dissociates in water, i.e.
HCl -log [10 - 3] = 3 |
[H +] + Cl -
