The first expression is the case with low concentration at low temperature probably. It is listed as follows: If you look in the dictionary nitrite. I exist only in (1) dilute solution. polyester Decomposes rapidly in nitric oxide and nitric polyester acid (2) in aqueous solution. Do not create the salt is present in an equilibrium polyester that 2HNO2 H2O + NO2 + NO in HNO3 +2 NO + H2O 3HNO2 (4) the gas phase in a dilute solution can be obtained and lead the nitric oxide 3HNO2 HNO3 +2 NO + H2O (3) nitric acid solution (5) polyvalent metal (usually Na salt, K salt comes out) it will change to NO and HNO3 in (2) HNO2 even if caused by the formula polyester above if the amount of NO2 to dissolve in water in many cases. You will be out of the water because NO is not soluble in water. Gas will occur when the reaction of nitric acid and copper. NO gas is colorless, but came out NO2 because it is brown you can see something. It's becoming to NO2 NO colorless reacts with air also you can see to the eye. equation below comes out when I combine the formula (2) and the above equation. That the above formula is written in the case of investigation of nitrogen oxide in the air pollution is often. polyester Expressions that come out as a manufacturing method of nitric acid is an expression of under. Repeat the reaction that dissolves in water also becomes NO2 NO that occurred and shake well with the addition of water to the test tube containing the NO2 reacts with oxygen in the air. You can get a NO If you collect the water replace the gas generated is reacted polyester with dilute nitric acid copper.
