Stoichiometry and a precipitation reaction
Review the following reaction, where sodium carbonate and calcium chloride dihydrate react in an aqueous solution to create calcium carbonate (solid precipitate formed in the reaction), a salt (sodium chloride), and water. Na2CO3(aq) + CaCl2⋅2H2O → CaCO3(s) + 2NaCl(aq) + 2H2O(aq) Na2CO3(aq) + CaCl2⋅2H2O → CaCO3(s) + 2NaCl(aq) + 2H2O(aq) Put on your safety gloves and goggles. Use the graduated cylinder to measure 25 ml […]
