8.20—Solution concentrations, in mol dm-3 and g dm-3

Be able to calculate solution concentrations, in mol dm-3 and g dm-3, including simple acid-base titrations using the indicators methyl orange and phenolphthalein.

Use —solution concentrations, in mol dm-3 and g dm-3 to connect the rule to the data and decision in the question.

This matters because —solution concentrations, in mol dm-3 and g dm-3 determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —solution concentrations, in mol dm-3 and g dm-3 to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Solution concentrations, in mol dm-3 and g dm-3 is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
