An organic acid has a problem in that it may have a relatively low pH at first, but after it dissolves a bit of the $\ce{CaCO3}$, a significant amount of the acid anion is formed in the solution, which stifles the ionization of the acid, so the rate of dissolution slows down. Chalk doesnot dissolve in water. These mild acids can dissolve rocks that contain calcium carbonate. A tiny proportion of the chalk will dissolve and another tiny proportion may react with dissolved carbon dioxide (in the form of carbonic acid).
