关于酸、碱化学性质的探究实验,同学们在学习时应该注意以下几点。1.实验体系的特点:这是以探究某种酸或碱的主要化学性质为目标的一类实验,也是和传统中学化学实验基本相同的一类实验。在“溶液酸碱性的检验”实验中,研究对象基本上都是呈酸性或碱性的稀溶液。这个实验用到的酸和碱虽然大都是酸、碱的稀溶液,但是为了探究它们的化学性质,使同学们能够
On the acid and alkali chemistry of the exploratory experiments, students should pay attention to the following points in the study. 1. Experimental system features: This is to explore the main chemical properties of a certain acid or alkali as the goal of a class of experiments, but also with traditional high school chemistry experiments are basically the same kind of experiment. In the “solution of acid-base test ” experiment, the object of study are basically acidic or alkaline dilute solution. Although most of the acids and bases used in this experiment were dilute solutions of acids and alkalis, to explore their chemistry, students were able to
