Making copper sulfate 1 Put 20 ml of sulfuric acid into a beaker. 2 Add a spatula of copper carbonate, stir it gently using a glass rod and look for bubbles. 3 When the reaction stops, repeat step 2. 4 Stop adding copper carbonate when no further bubbles form. 5 Filter the solution, carefully collecting the copper sulfate solution you have made in an evaporating dish. 6 Heat your solution gently over awater bath, stop when you see blue crystals forming.
To record Copper sulfate is also a salt, but this time we used a new chemical, copper carbonate, to provide the copper. When a metal carbonate reacts you get three products that are formed: metal carbonate + acid → salt + water + carbon dioxide (crystals) (evaporated) (bubbles)
To consolidate In our case we reacted copper carbonate with sulfuric acid: copper carbonate + sulfuric acid → copper sulfate + water + carbon dioxide 8B6 2 and 3 will help you to practise writing word equations for this new reaction.
Extend your chemistry Copper carbonate has the formula CuCO3 Sulfuric acid has the formula H2SO4 The balanced symbol equation for this reaction is: CuCO3 + H2SO4 → CuSO4 + H2O + CO2 See if you can write the balanced symbol equation for other metal carbonates such as CaCO3, SrCO3, BaCO3 and FeCO3. Don't forget to name the salt.
Extend your chemistry CaCO3 + H2SO4 → CaSO4 + H2O + CO2 SrCO3 + H2SO4 → SrSO4 + H2O + CO2 BaCO3 + H2SO4 → BaSO4 + H2O + CO2 FeCO3 + H2SO4 → FeSO4 + H2O + CO2
