Suggest what you would see when copper reacts with concentrated nitric acid.
Suggest the name of the salt with formula Cu(NO$_3$)$_2$.
Copper is oxidised when it reacts with concentrated nitric acid. Use the equation to explain why copper has been oxidised.
An excess of copper is added to 25.0 cm$^3$ of 16.0 mol/dm$^3$ HNO$_3$. Calculate the volume of NO$_2$ produced at room temperature and pressure.
When heated, Cu(NO$_3$)$_2$ breaks down to give CuO, NO$_2$ and O$_2$. Construct the equation for this reaction.
A student adds aqueous ammonia drop by drop to a sample of $\text{Cu(NO}_3)_2\text{(aq)}$ until the reagent is in excess. Describe what is seen.
The student repeats the experiment, but this time uses aqueous sodium hydroxide instead of aqueous ammonia. Describe what is observed.
