`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?

`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 an electrical conductor in its aqueous solution. Explain
Why is PCl_(5) more covalent than PCl_(3) ?
The product obtained on fusion of BaSO_(4) and Na_(2)CO_(3) is
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?
500mL of 0.25M Na_(2)SO_(4) solution is added to an aquesous solution is 15g of BaCl_(2) resulting in the formation of a white precipatate of insoluble BaSO_(4) . How many moles and how many grams of BaSO_(4) are formed.
Assertion : PCl_(5) is covalent in gaseous and liquid state but ionic in solid state. Reason: PCl_(5) in solid state consists of tetrahedral PCl_(4)^(+) cation and octahedral PCl_(6)^(-) anion.
