金属与硝酸反应是中学化学中氧化还原反应方面的一个重要计算。由此编制的计算题变化多端,思路广,隐蔽性解题难度大,本人从思维角度加以阐述,仅供参考。一、原子守恒法:可以解决金属或合金与硝酸的部分计算问题,利用金属的物质的量求出金属成盐所用的硝酸,进行一系列的计算n(消耗HNO3)=n(被还原HNO_3)+n(成盐HNO_3)例1.1.92g Cu与一定量的浓硝酸作用,当收集到1.12LNO和 The reaction of metals with nitric acid is an important calculation of redox reactions in secondary chemistry. The compilation of the calculation of the problem varied, broad thinking, concealed difficult problem-solving, I elaborate from a thinking point of view, for reference purposes only. First, the atomic conservation method: can solve the metal or alloy and nitric acid part of the calculation, the amount of metal used to determine the metal salt used in nitric acid, a series of calculations n (consumption of HNO3) = n (HNO3 reduction) + n (salt into HNO_3) Example 1.1.92g Cu with a certain amount of concentrated nitric acid, when collected 1.12LNO and
