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;

二、顺酐生产厂家下面来讲讲碳酸钠和碳酸氢钠的差异

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.
