Neco 2018 Chemistry Question 41
Practice objective / multiple choice question 41 from the 2018 Neco Chemistry examination.
Aluminium metal reacts with copper(II) sulphate according to \(2\,\mathrm{Al} + 3\,\mathrm{CuSO_4} \rightarrow \mathrm{Al_2(SO_4)_3} + 3\,\mathrm{Cu}\). A sample of 5.00 g Al is mixed with excess CuSO₄. The copper obtained is subsequently used to prepare copper(II) sulphate pentahydrate crystals, and 12.0 g of \(\mathrm{CuSO_4\cdot5H_2O}\) are isolated. Calculate the percent yield of copper in the first step.
