一、碳酸鈉和碳酸氫鈉的共性
1、 The commonality of sodium carbonate and sodium bicarbonate
1、都能與鹽酸(或硫酸與硝酸)反應(yīng)生成能使澄清石灰水變渾濁的氣體；
1. Both can react with hydrochloric acid (or sulfuric acid and nitric acid) to generate gas that can make clear lime water turbid;
2、跟石灰水或氫氧化鋇溶液都生成白色沉淀；
2. Generate white precipitates with lime water or barium hydroxide solution;
3、水溶液均呈堿性；
3. The aqueous solution is alkaline;
4、焰色反應(yīng)呈黃色；
4. Flame test is yellow;
5、都能與鋁鹽或鐵鹽溶液發(fā)生雙水解反應(yīng)；
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、熱穩(wěn)定性：碳酸鈉加熱不分解，碳酸氫鈉加熱易分解成碳酸鈉，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：碳酸鈉的溶解度大于碳酸氫鈉；
2. Water solubility: The solubility of sodium carbonate is greater than that of sodium bicarbonate;
3、與二氧化碳的反應(yīng)：碳酸鈉能跟二氧化碳(與水)化合生成碳酸氫鈉，而碳酸氫鈉不反應(yīng);
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、與氫氧化鈉的反應(yīng)：碳酸氫鈉能跟氫氧化鈉反應(yīng)生成碳酸鈉和水，而碳酸氫鈉不反應(yīng)；
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、與氯化鈣的反應(yīng)：碳酸鈉跟氯化鈣(或氯化鋇)溶液易生成碳酸鹽沉淀，而碳酸氫鈉跟鹽類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、與苯酚的反應(yīng)：碳酸鈉能與苯酚反應(yīng)生成苯酚鈉和碳酸氫鈉，而碳酸氫鈉不與苯酚反應(yīng)。
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.
