Hydrated copper(II) sulfate, CuSO4⋅5H2O\text{CuSO}_4 \cdot 5\text{H}_2\text{O}CuSO4⋅5H2O, is a blue crystalline solid. Anhydrous copper(II) sulfate, CuSO4\text{CuSO}_4CuSO4, is a white solid. Heat energy is required to decompose hydrated copper(II) sulfate into anhydrous copper(II) sulfate and water. This is a reversible reaction represented by the equation:
CuSO4⋅5H2O(s)⇌CuSO4(s)+5H2O(g) \text{CuSO}_4 \cdot 5\text{H}_2\text{O}(\text{s}) \rightleftharpoons \text{CuSO}_4(\text{s}) + 5\text{H}_2\text{O}(\text{g}) CuSO4⋅5H2O(s)⇌CuSO4(s)+5H2O(g)Devise an experiment to demonstrate that this is a reversible reaction.
Practise Edexcel GCSE Chemistry Reversible reactions and equilibria with exam-style questions for Foundation and Higher tier. 38 questions, matched to the Edexcel GCSE Chemistry (1CH0) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
