A student
0 1 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.

.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 =
maximum theoretical mass of salt that could be produced
×100
[3 marks]
Mass of salt actually produced = g
