Question

Q) The formula of chloride of a metal M is MCl3, then the formula of the hydroxide of metal M will be,

1)M2OH
2)M(OH)3
3)M2OH3
4)M(OH)2​

Answer 1

Answer:

M2oh is maybe right.

as you know hydrogen have 1 atomic number

Answer 2

Answer:

If the formula of a chloride of a metal Mis MC13, then the formula of the phosphate of Metal M will be MPO4. Since, the formula of a chloride of a metal M is MC13 , the metal is trivalent (because chlorine is monovalent ) Phosphate is trivalent .
