Recall the general equation for an acid + metal carbonate reaction

The general equation for an acid reacting with a metal carbonate is:

Acid + Metal Carbonate → Salt + Water + Carbon Dioxide

In chemical terms, it can be represented as:

H+(aq) + CO3^2-(s) → M+(aq) + X-(aq) + H2O(l) + CO2(g)

Where:

• H+ represents the hydrogen ion from the acid.
• CO3^2- represents the carbonate ion from the metal carbonate.
• M+ represents the metal ion from the metal carbonate.
• X- represents the anion from the acid.
• H2O represents water.
• CO2 represents carbon dioxide.
