What is the coordination number and oxidation state of Al in the complex `[AI(H_(2)O)_(4)(OH)_(2)]^(o+)`? .

Explanation

Coordination number of Al in `[A1(H_(2)O)_(4)(OH)_(2)]o+ is 6 To`
calculate oxidation state of Al in `[A1(H_(2)O)_(4)(OH)_(2)]^(o+)`
Charge on `H_(2)O` is 0 (zero) and on `OH` is `-1`
Let the charge on Al be x
`:. X + 0 xx 4 + (-1) xx 2 = + 1`
`implies x = +3`
Oxidation state of `A1` in `[A1 (H_(2)O)_(4)(OH)_(2)]^(o+)is + 3` .
