一、碳酸钠和碳酸氢钠的共性
1、 The commonality of sodium carbonate and sodium bicarbonate
1、都能与盐酸(或硫酸与硝酸)反应生成能使澄清石灰水变浑浊的气体;
1. Both can react with hydrochloric acid (or sulfuric acid and nitric acid) to generate gas that can make clear lime water turbid;
2、跟石灰水或氢氧化钡溶液都生成白色沉淀;
2. Generate white precipitates with lime water or barium hydroxide solution;
3、水溶液均呈碱性;
3. The aqueous solution is alkaline;
4、焰色反应呈黄色;
4. Flame test is yellow;
5、都能与铝盐或铁盐溶液发生双水解反应;
5. Both can undergo double hydrolysis reactions with aluminum or iron salt solutions;
2、 Maleic anhydride manufacturers will now discuss the differences between sodium carbonate and sodium bicarbonate
1、热稳定性:碳酸钠加热不分解,碳酸氢钠加热易分解成碳酸钠,水和二氧化碳;
1. Thermal stability: Sodium carbonate does not decompose when heated, while sodium bicarbonate easily decomposes into sodium carbonate, water, and carbon dioxide when heated;
2、水溶解性:碳酸钠的溶解度大于碳酸氢钠;
2. Water solubility: The solubility of sodium carbonate is greater than that of sodium bicarbonate;
3、与二氧化碳的反应:碳酸钠能跟二氧化碳(与水)化合生成碳酸氢钠,而碳酸氢钠不反应;
3. Reaction with carbon dioxide: Sodium carbonate can combine with carbon dioxide (with water) to form sodium bicarbonate, while sodium bicarbonate does not react;
4、与氢氧化钠的反应:碳酸氢钠能跟氢氧化钠反应生成碳酸钠和水,而碳酸氢钠不反应;
4. Reaction with sodium hydroxide: Sodium bicarbonate can react with sodium hydroxide to generate sodium carbonate and water, while sodium bicarbonate does not react;
5、与氯化钙的反应:碳酸钠跟氯化钙(或氯化钡)溶液易生成碳酸盐沉淀,而碳酸氢钠跟盐类稀溶液不易生成沉淀
5. Reaction with calcium chloride: Sodium carbonate and calcium chloride (or barium chloride) solution are prone to generating carbonate precipitates, while sodium bicarbonate and dilute salt solutions are not prone to generating precipitates
6、与苯酚的反应:碳酸钠能与苯酚反应生成苯酚钠和碳酸氢钠,而碳酸氢钠不与苯酚反应。
6. Reaction with phenol: Sodium carbonate can react with phenol to produce sodium phenolate and sodium bicarbonate, while sodium bicarbonate does not react with phenol.
