Calculating the pH of a Strong Base

Edexcel A-level ChemistryAcids, Bases and BuffersLesson 10 of 16

The strength of a base is its ability to dissociate and generate OH- ions in solution. Strong bases are alkalis. They dissociate completely to give hydroxide ions and cations. For example, sodium hydroxide is a strong base.

NaOH(aq) → Na+(aq) + OH-(aq)
