Chemical Bonding And Molecular Structure Question 130

Question: The sulphate of a metal has the formula $ M_2{{( SO_4 )}_3}. $ The formula for its phosphate will be

[DPMT 1982; CPMT 1972; MP PMT 1995]

Options:

A) $ M{{( HPO_4 )}_2} $

B) $ M_3{{( PO_4 )}_2} $

C) $ M_2{{( PO_4 )}_3} $

D) $ MPO_4 $

Show Answer

Answer:

Correct Answer: D

Solution:

Yet the formula of sulphate of a metal (M) is $ M_2{{(SO_4)}_3} $ , it is $ {M^{3+}} $ ion so formula of its phosphate would be $ MPO_4 $ .
