A test syllabus 1. To understand the main properties and uses of common acid-base, to know the corrosive acid and alkali. 2. Preliminary learn the common acid-base solution dilution method. 3. Understand acid-base indicator (phenolphthalein, litmus) and p H test strip test solution acid-base method. 4. Know the impact of pH on human health and crop growth. Case Study 1 (2015 · Huanggang) Building a model and building a knowledge network is an important learning method in chemistry learning. Li Hua students use the left hand to construct an acid property knowledge network. As shown in the figure, please answer the following questions :
