Worked Solution & Example Answer:A metal carbonate reacts with an acid - OCR Gateway - GCSE Chemistry: Combined Science - Question 2 - 2018 - Paper 1
Step 1
What products are made?
Answer
When a metal carbonate reacts with an acid, the products formed are a salt, carbon dioxide, and water. This is a typical reaction in which the acid donates protons (H+) to the carbonate (CO3^2-) to produce the salt and release carbon dioxide (CO2) gas, resulting in water (H2O) as well. Therefore, the correct answer is:
C Salt, carbon dioxide and water.
