This article concludes that nitrous acid is weak, monobasic, inorganic acid. HNO2 is a weak acid. It is used to treat the cyanide poisoning. Weak acids and bases are lower in energy than strong acids and bases, and because equilibria favor the reaction side with the lowest-energy species, acid-base reactions will go to the side with the weakest acids and bases. The strong bases are listed at the bottom right of the table and get weaker as we move to the top of the table. What is the unemployment rate for engineers? Expert Answer. This theory said that a substance behaves as an acid when it is ready to give off the hydrogen ion on dissolving in an aqueous solution. Figure 16.6.5: pH paper indicates that a 0.1-M solution of NH 3 (left) is weakly basic. FePO3 - insoluble. So, NO3 electron has a greater volume to stabilize the charge than the NO2. So, nitrogen is in higher oxidation state in nitric acid than in nitrous acid hence, becomes stronger acid. If A2- is more stable than A1-, then HA2 is probably a stronger acid than HA1. Nitrogen dioxide is an acidic gas. If A2 is more stable than A1-, HA2 is most likely a stronger acid than A1. For example HCl, H2SO4, HNO3 and so on.in case of HNO2 it do not dissociate completely in water. So, there is no weak base present to consume acid when acid is added, and there is no undissociated acid present to replenish . As a result, the H, which is attached to an outer O, loses more of it, weakening the OHbond. For example BF3, Ag+. pKa=3.33, Nitrous acid and Water reaction produces ions, but there is Also the HNO2 has dissociation constant (ka) is 5.610-4 which is very less than one mean that nitrous acid is weak acid. Aweak acid is any acid that is not one of the seven strong (e.g. Weaker bond = stronger acidity. Definition of a weak acid. Why does equilibrium favor the weaker acid? The weaker the weak acid the stronger it?s conj base. However, HNO2 (shown in Figure 18) is easier to prepare by the addition of an acid to a solution of nitrite; nitrous acid is a weak acid, so the nitrite ion is basic in aqueous solution: NO2 (aq) + H3 O +(aq) HNO2 (aq) + H2 O(l) Nitrous acid is very unstable and exists only in solution. As per Bronsted-Lowry theory, HNO2 is acid and donates one proton to a water molecule and forms a base(NO2) known as the conjugate base of an acid(HNO2).
