氢氧化钠、氢氧化钙因溶解性、腐蚀性及所含阳离子等方面的不同而使二者存在差异。二者对应的碳酸盐都能与酸反应产生二氧化碳,碳酸钠易溶于水且溶液显碱性,而碳酸钙难溶于水。例1 发现问题小明在学习中发现:检验 CO_2常用饱和 Ca(OH)_2溶液,吸收 CO_2则用浓 NaOH 溶液。实验探究在盛满 CO_2的容积相同的两集气瓶
Sodium hydroxide and calcium hydroxide are different due to differences in solubility, corrosion, and cations contained therein. Both of the corresponding carbonates can react with acid to produce carbon dioxide. Sodium carbonate is easily soluble in water and the solution is alkaline, whereas calcium carbonate is hardly soluble in water. Example 1 Found that the problem Xiaoming found in the study: test CO 2 commonly used saturated Ca (OH) 2 solution, absorption of CO 2 with concentrated NaOH solution.
