Is HNO2 ionic or molecular?

Nitrous acid HNO2 cannot be isolated as a pure compound. In the gas phase molecules of HNO2 are covalently bonded. In water it is a weak acid forming the nitrite ion however it readily disproportionates:- 3HNO2 -> H3O+ + NO3- + NO


How NOCl reacts with water?

The reaction with water is "messy"- initially hydrochloric acid and nitrous acid are formed. Oxygen from the air will oxidise and produce nitric acid and you may even get reddish fumes of NO2 that depends on how much water is present to "mop up" the NO2 NOCl +H2O ----> HNO2 + HCl (nitrous acid and hydrochloric acid) The HNO2 nitrous acid will disproportionate: 3HNO2 -> OH3+ + NO3- + 2NO Oxygen present in the water will react with the NO (nitric oxide) 2NO + O2 ->2NO2 NO2 will hydrolyse to form nitric and nitrous acid:- 2NO2 +H2O -> HNO3 + HNO2 A net equation in lots of water with sufficient O2 from the air will go right through to nitric acid and HCl


What is the equation for how solid chromium III hydroxide reacts with nitric acid ionic?

The equation for the reaction between solid chromium (III) hydroxide and nitric acid can be written as Cr(OH)3(s) + 3HNO3(aq) → Cr(NO3)3(aq) + 3H2O(l). In this neutralization reaction, the solid chromium (III) hydroxide reacts with the nitric acid to form chromium (III) nitrate and water.
