| Abstract: | An experimental method is successfully used to distinguish the sodium carbonate and sodium hydrogen carbonate solution by mercuric chloride,and its feasibility is demonstrated theoretically.The results show that the soda and dicarbonate solution in macroconcentration can be distinguished effectivly by mercuric chloride solution with sodium chloride.This method possesses the following advantages: simple of instrument and convenient operation,obvious experimental phenomenon,high success rate and good experimental effect. |
