—Analyse data from the following experiments: i measuring the pH of a variety of substances

Be able to analyse data from the following experiments: i measuring the pH of a variety of substances, including equimolar solutions of strong and weak acids, strong and weak bases, and salts ii comparing the pH of a strong and weak acid after dilution 10, 100 and 1000 times.

Use —analyse data from the following experiments: i measuring the ph of a variety of substances to connect the rule to the data and decision in the question.

This matters because —analyse data from the following experiments: i measuring the ph of a variety of substances determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —analyse data from the following experiments: i measuring the ph of a variety of substances to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Analyse data from the following experiments: i measuring the pH of a variety of substances is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
