(3)m(Na2CO3•nH2O)=8.50g-6.72g=1.78g,浓硫酸增重质量等于碳酸氢钠、碳酸钠晶体加热分解生成水的质量,由2NaHCO3((\;\;△\;\;))/(\;)Na2CO3+CO2↑+H2O,可知碳酸氢钠加热分解生成水的物质的量n(H2O)=n(CO2)=0.04mol,故碳酸钠晶体加热分解生成水的质量为1.78g-0.04mol×18g/mol=1.06g,故碳酸钠...
212 new data points for solubility and density have been measured in the mixed solvent electrolytic CO2−NaHCO3−Na2CO3−monoethylene glycol (MEG)−water system. Measurements were conducted at 2−60 °C at atmospheric pressure. An overview of methods available for determining the carbon ...
