WebCooling by solar energy is one of the key solutions to the global energy and environmental degradation issues. Solar liquid desiccant based on evaporative cooling is proposed as an eco-friendly alternative to the conventional vapour compression systems due to its huge untapped energy savings potential. WebAnhydrous CaCl2 is used as a desiccator. It removes water from the atmosphere within the desiccator to form a hydrate. A 16.43g CaCl2 sample has a mass of 21.75g after being left in a desiccator for several weeks. What is the formula of the hydrated CaCl2 salt? Show your calculations.

Web19 okt. 2024 · Is dissolving CaCl2 in water a chemical change? The dissolution of calcium chloride is an exothermic process. To help them understand why dissolution is a physical process, remind them that when they dissolve salt in water, they can still taste the salt. If the water were to evaporate, the salt would remain. WebCalcium chloride is available commercially in both anhydrous (CaCl2) and hydrated forms (CaCl2 H2O, CaCl2 2H2O, CaCl2 4H2O, CaCl2 6H2O). Any of them can be used to prepare 1 M calcium chloride stock solution. Anhydrous calcium chloride is solid white powder at room temperature.
