Chemical Bonding And Molecular Structure Question 112
Question: Formula of a metallic oxide is $ MO. $ The formula of its phosphate will be [CPMT 1986, 93]
Options:
A) $ M_2{{( PO_4 )}_2} $
B) $ M( PO_4 ) $
C) $ M_2PO_4 $
D) $ M_3{{( PO_4 )}_2} $
Show Answer
Answer:
Correct Answer: D
Solution:
Valency of metal is + 2 by formula MO so its phosphate would be $ M_3{{(PO_4)}_2} $ because valency of $ [PO_4] $ is - 3.
