    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)  (b) How many types of salts does dibasic acid produce when it reacts with caustic soda solution? Give equation(s) 
    Ans : 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 (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
