    (a) Give a balanced equation for reaction of nitrogen dioxide with water.  (b) How many types of salts does dibasic acid produce when it reacts with caustic soda solution? Give equation(s)  (a) Give a balanced equation for reaction of nitrogen dioxide with water.  (b) How many types of salts does dibasic acid produce when it reacts with caustic soda solution? Give equation(s) 
    Ans : 8 (a) 2NO2  + H2O → HNO2  + HNO3 (b) Two types of salts are produced when dibasic acid reacts with caustic soda. One is acidic salt and other normal salt.
    Acid salts:
    H2SO4 + NaOH → NaHSO4 + H2O
    Normal salts:
    H2SO4 + 2NaOH → Na2SO4 + 2H2O (a) 2NO2  + H2O → HNO2  + HNO3 (b) Two types of salts are produced when dibasic acid reacts with caustic soda. One is acidic salt and other normal salt.
    Acid salts:
    H2SO4 + NaOH → NaHSO4 + H2O
    Normal salts:
    H2SO4 + 2NaOH → Na2SO4 + 2H2O
