Suggest what you would see when copper reacts with hot concentrated aqueous sulfuric acid.
Name the salt with formula $\text{CuSO}_4$.
Copper is oxidised when it reacts with concentrated sulfuric acid. Use the equation to explain how copper has been oxidised.
An excess of copper is added to $25.0\,\text{cm}^3$ of hot $14.0\,\text{mol dm}^{-3}\,\text{H}_2\text{SO}_4$. Use this information, together with the equation, to calculate the greatest possible volume of $\text{SO}_2$ made. The gas volume is measured at room temperature and pressure.
Describe what would be observed when aqueous sodium hydroxide is added one drop at a time until it is in excess.
The student repeats the test, but aqueous ammonia is used instead of aqueous sodium hydroxide. Describe what would be observed.
Copper(I) chloride, $\text{CuCl}$, decomposes to give $\text{CuCl}_2$ and $\text{Cu}$. Write the equation for this reaction.
