BaSO4 is ionic and PCl3 is covalent but ...

`BaSO_4` is ionic and `PCl_3` is covalent but a saturated solution of `BaSO_4` is a weak electrolyte, while that the `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.

PCl_(3) is covalent. It fumes in moisture and its aqueous solution is electrical conductor. Why?

Explain the term: Strong and weak electrolytes

A solution which remains in equilibrium with undissolved solute is said to be saturated. The concentration of a saturated solution at a given temperature is called solubility. The product of concentration of ions in a saturated solution of an electrolyte at a given temperature, is called solubility product (K_(sp)) . For the electrolyte, A_(x),B_(y),:A_(x),B_(y(s)) rarr xA^(y+)+ y^(Bx-) , with solubility S, the solubility product (K_(sp)) =x^(x)xxy^(y) xx s^(x+y) . While calculating the solubility of a sparingly soluble salt in the presence of some strong electrolyte containing a common ion, the common ion concentration is practically equal to that of strong electrolyte. If in a solution, the ionic product of an clectrolyte exceeds its K_(sp) , value at a particular temperature, then precipitation occurs. The solubility of BaSO_(4) , in 0.1 M BaCl_(2) , solution is (K_(sp) , of BaSO_(4), = 1.5 xx 10^(-9))
