引用第1楼艺术就是爆炸于2011-09-17 22:52发表的 :买一包苏打粉，加68%硝中和，得到硝酸钠，可以代替硝酸钾，但要密封保存，硝酸钠吸湿性比硝酸钾强，做出来的烟雾弹更是，露天放一晚上就化成水了

没有Na2NO3此物质（据说是因为N的+4价不能稳定存在于酸中，或者变成+5价，或者变成+3价）硝酸钠：NaNO3亚硝酸钠：NaNO2亚硝酸钠+盐酸： NaNO2 + HCl = NaCl + HNO2

用稀硫酸的话，硝酸钾那组应该也不会变色，高氯酸钾我不太确定稀硝酸氧化碘离子只在热力学可行，在动力学不可行。因为稳定性较高，不易形成过渡态，而较浓的硝酸和亚硝酸的稳定性差，会反应高氯酸的应该也是这个原因
