The acidic waste from a students experiment needs to be disposed of, but puring it down the sink would increase the impact of acid rain on the local water supply. Explain how you could determin ethe amount of limestone needed to neutralize the environmental impact of the experiment (assume that the limestone is mainly calcium carbonate). Wrtie balanced equations for any reactions you intend to use

You would need to know the number of acid molecules that need to be neutralized, and the number of H+ (hydronium ions) donated by the acid. CaCO3 has the ability to accept two protons (hydronium ions) from the acid. You would need a number of CaCO3 molecules equal to 1/2 the number of hydronium ions from the acid.

Just dump the whole container of CaCO3 onto the acid, I'm sure that'll be plenty.
