M2 (CO3)3 is the sulphate of metal ‘M’. Write the formula of its phosphate, hydroxide and Oxide |
|
Answer» tion:For given FORMULA of SULPHATE of metal, its valency is +2.(i) OH − is hydroxide ion. By balancing charge, formula of metal hydroxide ion is M(OH) 2 .(ii) ClO 2− is chlorite ion. We need 2 such ions for charge balance. Hence metal chlorite M(ClO 2 )2.(III) Chloride has Cl − ion. Hence, metal chloride is MCl 2 .(iv) NO 3− is nitrate ion. By charge balance, metal nitrate is M(NO 3 ) 2 .(v) NO 2− is nitrite ion. Hence M(NO 2 ) 2 is metal nitrite.(vi) Peroxide has O − ion. By charge balance, metal peroxide is MO 2 .(vii) CrO 42− is chromate ion. Hence, by balancing charges metal chromate is M(CrO 4 ).(VIII) (PO 4 ) 3− is phosphate ion. By charge balance, metal phosphate is M 3 (PO ) 2 . |
