(a) When sugar is heated.
(b) When manganese dioxide is added to
potassium chlorate and heated.
(c) When dilute acetic acid is poured on baking soda
(d) When an aqueous solution of sodium chloride is
mixed with an aqueous solution of silver nitrate​

Answer 1

Explanation:

Aqueous solution of NaCl contains equal number of H+ and OH- ions,hence it is neutral in nature. On other hand,sodium carbonate is a salt of weak acid H₂CO₃ and strong base NaOH. When it is dissolved in water,it undergo anionic hydrolysis. Thus salt solution contains OH- ions.
