碳酸钠是钠的一种重要的化合物,是一种白粉末状固体,俗称纯碱或苏打。盐酸是实验室最常用的三强酸之一,碳酸钠与盐酸的反应,也是高考考查的重要知识点,弄清它们之间反应的特点和规律对学好其他物质之间反应规律有很大的帮助和启示。 Na_2CO_3溶液与盐酸反应的特点:滴加顺序不同,现象不同,产物也不同。 1.若将盐酸逐滴加入Na_2CO_3溶液中,反应分两步进行:
Sodium carbonate is an important compound of sodium and is a white powdered solid commonly known as soda or soda. Hydrochloric acid is one of the most commonly used three-strength acids in the laboratory. The reaction between sodium carbonate and hydrochloric acid is also an important knowledge point for the college entrance examination. It is very helpful to understand the characteristics and laws of the reactions between them and to learn the laws of reaction between other substances. And inspiration. The reaction characteristics of Na 2 CO 3 solution and hydrochloric acid: different dropping sequences, different phenomena, and different products. 1. If hydrochloric acid is added dropwise to the Na2CO3 solution, the reaction proceeds in two steps:
