1. A certain town gets its water from an underground aquifer that contains water in equilibrium with limestone (calcium carbonate). One resident leaves town of vacation and in the process, leave a cup of water (200mL) on the kitchen table. When he returns, the water has evaporated, leaving only calcium carbonate in the cup. How much calcium carbonate in remaining in the cup and if the residents wants to clean the cup, is he better doing so with an acidic cleaner (like lemon juice) or a basic solution (like soap or baking soda)? Explain why and in your complete answer, include the following: a. equilibrium formula b. the Ksp value c. molar solubility of the calcium carbonate in the water d. how much calcium is present in the sample in grams? e. calculations presented in steps f. the interaction with the acid and/or base with the calcium carbonate
