14.9—The pH of a weak acid from Ka or pKa values, making relevant assumptions Students will not be expected to solve quadratic

Be able to calculate the pH of a weak acid from Ka or pKa values, making relevant assumptions Students will not be expected to solve quadratic equations.

Use —the ph of a weak acid from ka or pka values, making relevant assumptions students will not be expected to solve quadratic to connect the rule to the data and decision in the question.

This matters because —the ph of a weak acid from ka or pka values, making relevant assumptions students will not be expected to solve quadratic 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 weak acid from ka or pka values, making relevant assumptions students will not be expected to solve quadratic to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —The pH of a weak acid from Ka or pKa values, making relevant assumptions Students will not be expected to solve quadratic is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
