Question

How will you account for the acidic character of nitrous acid `(HNO_(2))` according to both Arrhenius theory and Bronsted-Lowry theory?

Answer 1

(i) The acidic character according to Arrhenius theory is indicated as follows:
`HNO_(2)(l) +H_(2)O hArr H^(+) (aq) +NO_(2)^(-) (aq)`
(ii) The acidic character according to Lowry-Bronsted concept is shown as follows:
`{:(HCO_(2)(l),+,H_(2)O ,hArr,H_(3)O^(+)(aq) ,+,NO_(2)^(-)(aq)),("Acid"-I,,"Base-II",,"Acid-II",,"Base-I"):}`
