The damage that acid rain does to limestone and marble buildings and sculptures is due to a classic acid–base reaction. Marble and limestone both consist of calcium carbonate (CaCO 3), a salt derived from the weak acid H 2 CO 3.As we saw in Section 4.7 the reaction of a strong acid with a salt of a weak acid goes to completion. Thus we can …

Introduction. Soil acidity is largely controlled by the composition of ions on exchange sites on the colloidal fraction. The H + cations are acidic by definition, and Al 3+ cations are considered acidic because they react with H 2 O to produce Al(OH) 3 and 3H +.The Ca 2+, Mg 2+, K +, Na + cations, among others, are considered basic because they form …

— Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more …
