我们都知道,硝酸具有强氧化性,而且硝酸在水溶液中本来就以离子形式存在,因此NO3-在酸性溶液中同样具有强氧化性。此知识虽不难,但因为在命题时增加了隐蔽性,因此在解题时常因忽视了NO3-在酸性溶液中具有强氧化性而不小心落入陷阱。
We all know that nitric acid is highly oxidizing and that nitric acid is inherently ionic in aqueous solution, so NO3- also has strong oxidizing properties in acidic solutions. Although this knowledge is not difficult, but because of increased secrecy in the proposition, so often neglected in the problem-solving NO3- in acidic solution with strong oxidizing and accidentally fall into the trap.
