Question

the formula of a chloride of a metal M is MCl3, the formula of the oxalate of metal M will be​

Answer 1

Explanation:

If the formula of a chloride of a metal M is MCl

3

, then the formula of the phosphate of metal M will be MPO

4

.

Since, the formula of a chloride of a metal M is MCl

3

, the metal is trivalent (because chlorine is monovalent). Phosphate is trivalent. Hence, one M

3+

ion will combine with one PO

4

3−

ion to maintain electrical neutrality.
