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;
5. Both can undergo double hydrolysis reactions with aluminum or iron salt solutions;
順酐廠家
二、順酐廠家下面來講講碳酸鈉和碳酸氫鈉的差異
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: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;
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:碳酸氫鈉能跟氫氧化鈉反應生成碳酸鈉和水,而碳酸氫鈉不反應;
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: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:碳酸鈉能與苯酚反應生成苯酚鈉和碳酸氫鈉,而碳酸氫鈉不與苯酚反應。
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.
