BaSO(4) is ionic and PCl(3) is covalent ...

`BaSO_(4)` is ionic and `PCl_(3)` is covalent but a saturated solution of `BaSO_(4)` is a weak electroyte, While that of `PCl_(3)` is a strong electrolyte. Explain?

Text Solution

Verified by Experts

`BaSO_(4)` has high lattice energy. It is very less soluble in water, even in saturated solutions. The ionic concentration is in the order of `10^(-5)M`. Hence it is a weak Electrolyte.
`PCl_(3)` is covalent. It undergoes hydrolysis in water to give hydrochloric acid. Which is a strong electrolyte.

The product obtained on fusion of BaSO_(4) and Na_(2)CO_(3) is

`BaCO_(3)`

BaO

`Ba(OH)_(2)`

`BaHSO_(4)`

Na_(2)SO_(4) is soluble in water while BaSO_(4) is sparingly soluble because

The Littice energy of `BaSO_(4)` is more than its hydration energy.

The hyration energy and the lattice energy have no role tp play in the solubilty of a substance

The hydration energy of `Na_(2)SO_(4)` is more than its lattice energy.

Both A and C

Let C_(NaCl) and C_(BaSO_(4)) be the conductances (in S) measured for saturated aqueous solutions of NaCl and BaSO4, respectively, at a temperature T. Which of the following is false?

`C_(NaCl)(T_(2))gtC_(NaCl)(T_(1))" for "T_(2) gt T_(1)`

`C_(BaSO_(4))(T_(2))gtC_(BaSO_(4))(T_(1))" for "T_(2) gt T_(1))`

Ionic mobilities of ions form both salts increase with T.

`C_(NaCl)gt gt C_(BaSO_(4))` at a given T
