1.	X is pale yellow solid, It hydrolyess to POCl_(3) in moist air and finally gets converted into phosphoric acid. X exists as an ionic solid. The total number of atoms present in its cation is.
Answer» Solution :`underset((X))(PCl_(5))+H_(2)OtoPOCl_(3)+2HCl,` `POCl_(3)+3H_(2)OtoH_(3)PO_(4)+3HCl` In the solid STATE, `PCl_(5)` (X) EXISTS as `[PCl_(4)]^(+)[PCl_(6)]^(-)` in which the CATION has 5 atmos (4Cl+1P).
