When EDTA solution is added to `Mg^(2+)` ion solution then the incorect statement regarding the reaction will beA. Four coordinate sites of `Mg^(2+)` are occupied by EDTA and remaining two sites are occupied by water moleculesB. All six coorinate sites of `Mg^(2+)` are occupiedC. pH of the soluiton is decreasedD. Colourless `[Mg-EDTA]^(2-)` chelate is formed |

Answer» Correct Answer - A `[H_(2)EDTA]^(2-)+Mg^(2+) rarr [Mg-EDTA ]^(2)+2H^(+)` (i) In this complex, four donor sites are occupied by oxygen and two donor sites are occupied by hydrogen. (ii) This complex is six coordinated. (iii) Complex `[Mg-EDTA]^(2-)` is colourless. (iv) Increase in `[H^(+)]` decreases pH of the solution |
