# Does salts react with acids?

 P: 13 I am new to the concepts of reaction between of Acids, Bases and Salts. While learning, I notice that some salts react with acids to form a new salt (and sometimes a new acid is produced), especially in Qualitative Analysis, while some don't even reacts. I tried to search the internet about it but to no avail, I've no choice but to ask you guys. Why is it that some salts do not react with acids? Is it because of it's solubility in water or other reasons? That also contradicts me because $$CuCO_3$$ + $$H_{2}SO_4$$ $$\longrightarrow$$ $$CuSO_4$$ + $$H_2O$$ + $$CO_2$$ $$CuCO_3$$ is an insoluble salt, but it is still able to react with acids. Why do salts even react with acids in the first place, that doesn't make sense to me. For example if $$CaNO_{3}$$ reacts with $$HCl$$ to produce $$CaCl_2$$and $$HNO_3$$, why woundn't the $$CaCl_2$$ reacts with $$HNO_3$$ again to form back $$CaNO_{3}$$ and $$HCl$$?
