“中和反应”是初中化学学习的重点,同时也是中考化学热点之一,有关“中和反应”的考题在近年来的中考中频频出现,它们从不同的视角、以不同的形式对中和反应的内涵进行了考查,体现了命题的灵活性和新颖性,现例析几题,供大家参考.例1 向盛有10mL 稀盐酸(其中滴有少量紫色石蕊试剂)的烧杯中加入氢氧化钠溶液,用 pH 计(测pH 的仪器)测定溶液的 pH,所得数据如下.请分析并 “Neutralization reaction” is the focus of junior middle school chemistry learning, and it is also one of the chemical hotspots in the middle school entrance examination. The questions about “neutralization reaction” have frequently appeared in the midterm examinations in recent years. They differ from different perspectives and in different ways. The form has examined the connotation of the neutralization reaction, which reflects the flexibility and novelty of the proposition. Samples are analyzed for reference. For example, there are 10 mL of dilute hydrochloric acid (which contains a small amount of purple litmus reagent). The sodium hydroxide solution was added to the beaker and the pH of the solution was measured using a pH meter (instrument for measuring pH). The data obtained was as follows. Please analyze and
