Question

The chloride of a metal has the formula MCl3. The formula of its phosphate will be:
(a) M2PO4 (b) MPO4 (c) M3PO4 (d) M (PO4)2....PLZ ANS WITH FORMULA AND STEPS

Answer 1

mpo4
since MCl3 means M3+ and 3Cl-
and PO4 has a charge of 3-
so M3+ + PO43- gives MPO4

Answer 2

Since the Chloride of the formula is MCl3, we get that the valency of the metal is +3.

Therefore the correct answer for the phosphate of the chloride is given in option ‘b” which is MPO4.

Since MCl3 means, the formula has M3+ and 3Cl-

And PO4 has a charge of 3- which is negative,

Therefore  M3+ + (PO4)3- is equal to MPO4
