説明
Nitrous acid (molecular formula?HNO2) is a weak and monobasic acid known only in solution and in the form of nitrite salts. Nitrous acid rapidly decomposes into nitrogen oxide, nitric oxide and water when in solution:2HNO2 ? NO2 + NO+H2O
It can also decompose into nitric acid and nitrous oxide and water.
4HNO2 ? 2HNO3 +N2O +H2O
Nitric acid (HNO3), also known as “aqua fortis” and “spirit of nitre”, is a highly corrosive and toxic strong acid that can cause severe burns. It is colorless when pure and a slight yellow when “glacial”. Older samples tend to acquire a yellow cast due to the accumulation of various oxides of nitrogen. If the solution contains more than 86% nitric acid, it is referred to as “fuming nitric acid”.
