A student produced a salt by reacting copper carbonate with sulfuric acid.
This is the method used.
- Measure 50 cm³ of sulfuric acid into a beaker.
- Add copper carbonate powder.
- Stir the mixture.
- Repeat steps 2 and 3 until copper carbonate is in excess.
- Filter the mixture.
- Warm the filtrate gently until crystals start to appear.
- Leave the solution to cool and crystallise.
Complete the word equation for the reaction.
copper carbonate + sulfuric acid → ______ + ______ + carbon dioxide

How to approach this question
This is a word equation for the reaction between a metal carbonate and an acid. Recall the general formula: Metal Carbonate + Acid → Salt + Water + Carbon Dioxide. Identify the metal from the carbonate and the salt name from the acid.
Full Answer
copper carbonate + sulfuric acid → copper sulfate + water + carbon dioxide
When a metal carbonate reacts with an acid, the products are a salt, water, and carbon dioxide. In this reaction, copper carbonate (CuCO₃) reacts with sulfuric acid (H₂SO₄). The metal from the carbonate (copper) combines with the non-metal part of the acid (sulfate) to form the salt, copper sulfate (CuSO₄). The other two products are always water (H₂O) and carbon dioxide (CO₂).
Common mistakes
✗ Forgetting to include water as a product.
✗ Naming the salt incorrectly, e.g., copper sulfide instead of copper sulfate.
