How do acids react with limestone and metal?

Answer 1

All the acids react with lime stone forming the calcium salt ,carbondioxide and water as, CaCO3 + 2HCl = CaCl2 + CO2 + H2O , the reactions with metals depends upon concentration of acid , nature of metal ,nature of acid and temperature as , Cu +4HNO3(conc.) = Cu(NO3)2 + 2NO2 + 2H2O 3Cu + 8HNO3 (dil.) = 3Cu(NO3)2 + 2NO + 4H2O Cu + H2SO4(dil) = No reaction Zn + H2SO4(dil) = ZnSO4 + H2

Answer 2

Acids react with limestone by a process called acid erosion, where the acid breaks down the calcium carbonate in limestone, creating calcium salts and releasing carbon dioxide gas. When acids react with metals, they can produce hydrogen gas and a metal salt. The reactivity of the metal with the acid will determine the rate and intensity of the reaction.
