Heat capacity of solutions by flow microcalorimetry A differential flow microcalorimeter has been designed for the measurement of heat capacities of solutions. Under steady-state condition, it is possible to obtain directly the ratio of the heat capacity of a solution to that of its solve... P ...
Dissolving 4.49 g of CaCl2 in enough water to make 252 mL of solution causes the temperature of the solution to increase by 3.77 oC. Assume the specific heat of the solution and density of the solution are the same as water?s (about 4.18 J/...
Soluble in water, while releasing a lot of heat, the aqueous solution is slightly acidic. Soluble in alcohol, acetone, acetic acid. With ammonia or ethanol, respectively, the formation of CaCl2 · 8NH3 and CaCI2 · 4C2 Hs OH complexes. At room temperature by aqueous solution crystallization...
A direct contact heat exchange method is utilized to enhance the overall heat transfer rate. Composite zeolite (CZ) is prepared by immersing zeolite particle in CaCl2 solution at mass concentration of 40%. Cyclic experiment consists of two processes: regeneration with 130 °C dry air and steam ...

(e.g. 1 atm). If an ionic compound is dissolved in the water, then there will exist strong ion-dipole interactions between the constituent ions and the water molecules. Additional heat energy will be required to boil the aqueous solution at the same pressure, relative to pure water...
Heat the second beaker which contains the calcium chloride solution. Solid calcium chloride is the solid left after the water evaporates. Calcium Chloride Solutions Calcium chloride is highly soluble in water, because of its high solubility it is used to obtain solutions having relatively high densiti...
