Ammonium chloride এর কাজ, ব্যবহারের নিয়ম

The colour of both barium chloride and sodium sulphate is white.

KCl (aq) + AgNO3 (aq) → AgCl (s) + KNO3 (aq) It is a double displacement and precipitation reaction.

Na atom get oxidize and Cl is reduced

(a) Magnesium chloride →MgCl2  (b) Calcium oxide →CaO  (c) Copper nitrate →Cu(NO3)2  (d) Aluminium chloride →AlCl3  (e) Calcium carbonate →CaCO3

Hint–  Step-1 Separate iron filings with the help of a magnet  Step-2 Sublimation of the remaining mixture separates ammonium chloride  Step-3 Add water to the remaining mixture, stir and filter  Step-4 The filtrate can...

Since dissolution of NH4Cl in water is endothermic process, its solubility increases with rise in temperature (i.e., Le-Chatelier process).

The correct answer is  (b)

It is used as detergents, e.g,[CH3(CH2)15N(CH3)2]+Cl-.

Ammonium chloride (NH4Cl) is the salt of a strong acid, hydrochloric acid (HCl), and a weak base ammonium hydroxide (NH4OH), so an aqueous solution of ammonium chloride is acidic in...
