0 1 A student produced a salt by reacting copper carbonate with sulfuric acid. box
This is the method used.
1. Measure 50 cm3 of sulfuric acid into a beaker.
2. Add copper carbonate powder.
3. Stir the mixture.
4. Repeat steps 2 and 3 until copper carbonate is in excess.
5. Filter the mixture.
6. Warm the filtrate gently until crystals start to appear.
7. Leave the solution to cool and crystallise.

acid is 12.5 g.
The percentage yield of the salt is 92.8%. Calculate
the mass of salt actually produced. Use the
equation:
mass of salt actually produced
% yield = ×100
maximum theoretical mass of salt that could be produced
[3 marks]
Mass of salt actually produced = g
