氧化还原反应是化学反应原理的重要内容,探究氧化还原反应原理是实验命题重要方向之一,涉及内容主要有:(1)探究物质氧化性或还原性与浓度、温度等因素关系;(2)氧化还原反应滴定原理应用等.例题:为了探究浓度对硫酸氧化性的影响,某学习小组进行了以下探究活动:探究一称取无锈铁钉(碳素钢)12.0g放
Oxidation-reduction reaction is an important part of the chemical reaction principle. It is one of the important directions of the experimental proposition to explore the principle of redox reaction. The main contents involved are: (1) to explore the relationship between the oxidation or reduction of the substance and the concentration, temperature and other factors; (2) Oxidation-reduction titration principle application etc. Example: In order to explore the effect of concentration on the oxidizing power of sulfuric acid, a learning group conducted the following exploration activities: to explore a weighed 12.0g of stainless steel nail (carbon steel)
