一、什么是“组合硝酸”向硝酸盐溶液中滴入盐酸或硫酸等酸性溶液,混合溶液中就有了H-和NO3-,这就是“组合硝酸”.或者说,非硝酸电离出来的H+与硝酸盐电离出来的NO3能组合成“硝酸”.
1. What is “combined nitric acid”? Dropping an acidic solution such as hydrochloric acid or sulfuric acid into a nitrate solution has H- and NO3- in the mixed solution. This is called “combined nitric acid.” Or, the non-nitric acid ionized H+. Nitric acid ionized NO3 can be combined into “nitric acid”.
