Final answer:
In the neutralization equation H₂CO₃ + Ca(OH)₂ → CaCO₃ + 2H₂O, carbonic acid is the acid, calcium hydroxide is the base, calcium carbonate is the salt produced, and water is also formed.
Step-by-step explanation:
The chemical equation H₂CO₃ + Ca(OH)₂ → CaCO₃ + 2H₂O represents a neutralization reaction, where an acid and a base react to form water and a salt. In this case, H₂CO₃ (carbonic acid) is the acid, Ca(OH)₂ (calcium hydroxide) is the base, CaCO₃ (calcium carbonate) is the salt, and 2H₂O represents the water formed. The acid and base undergo a double displacement reaction to yield the products.
