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.

0 1 . 5 The maximum theoretical mass of the salt that could be produced using 50 cm3 of the
sulfuric 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
