Objective

Level
A2

—The pH of a strong base from its concentration

Be able to calculate the pH of a strong base from its concentration, using Kw or pKw.

Use —the ph of a strong base from its concentration to connect the rule to the data and decision in the question.

This matters because —the ph of a strong base from its concentration determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —the ph of a strong base from its concentration to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —The pH of a strong base from its concentration is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
