Question

MCl is the formula of chloride of metal M . Write the formula of sulphate,oxide and nitrate

Answer 1

Answer:

So formula of metal sulphate will be - MSO4. MZn(OH)4. To form metal hydroxide, one ion of metal will react with two molecules of hydroxyl ions containing charge of -2. M(OH)2 will be the formula.

Answer 2

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.
