Using concentrations of solutions in mol/dm3 (chemistry only) (HT only)

Question

  1. A. formula and unit: (chemistry only) (HT only) Use titration data to determine concentrations of strong acids and alkalis. (AT 1, AT 3, AT 8)
  2. B. wrong formula: uses a different Unit 4.3 relationship from Concentrations in mol/dm3 and titration calculations
  3. C. wrong unit: gives a value without checking the required unit
  4. D. wrong reasoning: confuses coefficients, subscripts, mass, moles, or concentration

Answer

The correct option is formula and unit: (chemistry only) (HT only) Use titration data to determine concentrations of strong acids and alkalis. (AT 1, AT 3, AT 8).

Explanation

The correct option is formula and unit: (chemistry only) (HT only) Use titration data to determine concentrations of strong acids and alkalis. (AT 1, AT 3, AT 8). It is correct because it directly supports the approved learning objective to (chemistry only) (HT only) Use titration data to determine concentrations of strong acids and alkalis. (AT 1, AT 3, AT 8). This belongs to Concentrations in mol/dm3 and titration calculations within Using concentrations of solutions in mol/dm3 (chemistry only) (HT only), so the answer must use the named Unit 4.3 relationship and avoid mixing it with nearby ideas such as mass, moles, concentration, yield, atom economy, gas volume, coefficients, or subscripts.

Common mistake

Misunderstanding Titration Calculations

Students often confuse the volumes of acid and alkali used in titrations, leading to incorrect concentration calculations.

Always ensure to use the correct volume for each solution in the titration and double-check the balanced equation to find the correct mole ratio.
