The dissolution of ammonium chloride in water is endothermic process. What is the effect of temperature on its solubility ?

If temperature is high, then TΔS will be much greater than ΔH in magnitude so that ΔG is highly negative.

(i) Suppression of ionization of weak electrolyte by adding a strong electrolyte having an ion common.  (ii) Product of the molar concentrations of the ions in a saturated solution, each concentration...

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

Mass of solute (sodium chloride) = 36 g (Given)  Mass of solvent (water) = 100 g (Given)  Then, mass of solution = Mass of solute + Mass of solvent  = (36 + 100)...

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...

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...

(D) (ii) and (iv)

(B) reaction proceeds with fall in temperature Mixing of solid barium hydroxide [Ba(OH)2] and solid ammonium chloride [NH4Cl] in a ratio of 2 : 1 by weight at room temperature in...

(b) : For endothermic reaction, ΔH = +ve Now, ΔG = ΔH – TΔS For nonspontaneous reaction, ΔG should be positive Now ΔG is positive at low temperature if ΔH is positive. ΔG is negative...
