Question

Many homeowners treat their lawns with CaCO3(s) to reduce the acidity of the soil. Write a net ionic equation for the reaction of CaCO3(s) with a strong acid.

Answer 1

Many homeowners treat their lawns with CaCO3(s) to reduce the acidity of the soil. The net ionic equation for the reaction of CaCO3(s) with a strong acid, HCl (I chose HCl because it is a strong acid) is CaCO3(s) +2 HCl(aq) → CaCl2(s) + H2O(aq) + CO2(g).
