Please explain me the NOTE box
Dear student,
It is important to understand that the reactions that we study in our books actually occurs in a solution. That means that the substance that react with each other are in the dissolved state and not present in the solid state. Same is for the neutralization reaction between acid and base. Carbonate salts are slightly basic in nature and hence reacts with hydrochloric acid or sulphuric acid.
Now, since lead carbonate and calcium carbonate are insoluble in water, they do not even react with the acid present in water since they themselves do not dissolve in water.
So, hope this is clear,
Regards
