Question

A certain town gets its water from an underground aquifer that contains water in equilibrium with calcium carbonate limestone.

a.) Calculate the molar solubility of calcium carbonate (Ksp = 4.96×10^-9)

b.) If an entire coffee cup of water (about 200 mL) evaporated on your desk over spring break, how many grams of calcium carbonate would be left behind?

c.) If you wanted to clean out your coffee cup, would it be better to use an acidic or basic cleaning solution? Why?
