[3]
(b)Why salts when kept in open turn sticky during rainy season?​

Answer 1

Answer:

hey friend

here is ur answer

Explanation:

a)Solutions like HCl,HNO3etc. get ionised in aqueous solutions and due to the presence of H+ ions they show acidic characters.

While solutions of compounds like alcohol and glucose do not form any such ions so they do not show acidic characters.

b)Table salt is sodium chloride and some minute quantities of magnesium chloride. These salts are hygroscopic in nature resulting in absorbing moisture from the surroundings so it becomes sticky during rainy season.
