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

`CO_3^(2-) + H_3O^+ rarr HCO_3^(-) + H_2O(l)`

But carbonate ion is dibasic....

Explanation:

And.....

`HCO_3^(-) + H_3O^+ rarr CO_2(g)uarr +H_2O(l)`

Overall....

`CO_3^(2-)+2H_3O^+ rarr CO_2(g)uarr +2H_2O(l)`
