【Abstract】 Magnesium oxychloride sample （A） and （B） are obtained by the reaction between MgO and MgCl₂·6H₂O solution, The heat of solution of samples in 2.163mol/ L HCI aq. solution is determined by CALVET microcalorimeter. The heat of solution of （A） and （B） from the linear relationship between ratio nand heat of solution are derived and calculating their heat formation is then perfected.更多还原
