(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)

Answer»

(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
