Answered by admin @
Limestone is a mixture of the minerals calcite and aroganit , both of which form polymorphic form of calcium carbonate CaCo3. David compounds reacts with HCL as follows (standard acids- base reaction)
CaCo3 (s) + 2HCL (aq) gives rights to CaCl2 (aq) + Co2 (g) + H2O (l)
Carbon dioxide gas is produced and this makes the solution effervesce. An aqueous solution of calcium chloride & water is left behind
