生活中人们利用化学反应的事实很多,尤其是中和反应,如课本上介绍的中和过多的胃酸、改善土壤的酸碱性、处理工厂废水等。中和反应极大地丰富和改善了人们的实际生产和生活,下面介绍几个生活实例。实例一:云吞面是一种面食,俗称“碱水面”。吃云吞面时,很多人都会加点醋来调味。这是为什么呢?云吞面在制作过程中加入了碱水,碱水呈碱性,带点苦涩的味道;而我们加入的醋则含有醋酸,醋酸是酸性,两
There are many facts that people use chemical reactions in life, especially neutral reactions, such as the introduction of excessive stomach acid in the textbooks, improvement of acidity and alkalinity of the soil, and disposal of waste water from factories. Neutralization greatly enriches and improves people’s actual production and life. Here are some examples of life. Example one: Wonton noodles is a kind of pasta, commonly known as “alkaline surface”. When eating wonton noodles, many people will add some vinegar to season. Why is this?
