松花蛋是一种很受人们欢迎的、营养丰富的食品。剥开蛋壳,片片美丽的“松花”就会呈现在我们眼前。松花蛋是怎么制成的?为什么里面会有“松花”呢? 制松花蛋的主要原料是生石灰、纯碱、食盐、红茶叶、水和含有氧化钙、氧化钾的植物灰(你能写出这些化学物质的相应化学式吗?)。把原料按一定的比例混合制成料液(或料泥)时,发生了一系列化学反应,生成氢氧化钠、氢氧化钾、碳酸钙,并电离出氢氧根离子、钾离子、钠离子和钙离子(试着写出反应方程式)。
Songhua egg is a very popular and nutritious food. Peeling off the shells, beautiful “song flowers” will appear before our eyes. How are the preserved eggs made? Why are there “song flowers” inside? The main raw materials for making preserved eggs are lime, soda ash, salt, black tea leaves, water, and plant ash containing calcium oxide and potassium oxide (you can write these Corresponding Chemical Formula?). When raw materials are mixed in a certain proportion to make a liquid (or sludge), a series of chemical reactions take place, producing sodium hydroxide, potassium hydroxide, calcium carbonate, and ionizing hydroxide ions, potassium ions, and sodium ions. And calcium ion (try to write the reaction equation).
