Multiple Choice Questions

The solubility of in water is Sb₂S₃ in water is 1.0 x 10^-5 mol/litre at 298 K .What will be its solubility product ?

108 x 10^-25
1.0 x 10^-25
144 x 10^-25
126 x 10^-25

What will be the pH value of 0.05 M Ba(OH)₂ solution ?

12
13
1
12.96

Which of the following elements never show positive oxidation number ?

Which of the following element is a metalloid ?

Ionisation depends upon :

pressure
volume
dilution
none of these

The first ionisation potential is maximum for :

7.
Which of the following salt does not get hydrolysed in water ?

KClO₄

NH₄Cl

CH₃COONa

None of these

KClO₄

Only salts of (weak acid + strong base) and (strong acid + weak base) get hydrolysed (i.e., show alkalinity or acidity in water) . KClO₄is a salt of strong acid and strong base ,therefore it does not get hydrolysed in water .

KClO₄ $⇌$ K⁺ + ClO₄^-

H₂O $⇌$ $\underset{\overset{⥮}{\overset{KOH}{(strong)}}}{{OH}^{-}} + \underset{\overset{⥮}{\underset{(strong)}{{HClO}_{4}}}}{H^{+}}$

In the reaction :

H₂ + I₂ $⇌$ 2HI

In a 2 litre flask 0.4 moles of each H₂ and I₂ are taken .At equilibrium 0.5 moles of HI are formed .What will be the value of equilibrium constant ,K_c ?
