An engineer is designing a public swimming pool. she knows that the swimming pool will last longer if the liquid in it is a weak solution of calcium chloride. this solution will not erode the pool's sides as rapidly as pure water. however, when calcium chloride is added to the pool and as it dissolves, the water's temperature will rapidly increase according to the following chemical equation. cacl2 → ca2+ + 2cl- + heat what could the engineer do to reduce the temperature the water reaches when calcium chloride is added to it?
