When EDTA solution is added to `Mg^(2+)` ion solution then the incorect statement regarding the reaction will be

Options

A. Four coordination sites of `Mg^(2+)` are occupied by EDTA and remaining two statement j regarding sites are occupied by water molecules
B. all six coordination sites of ` Mg^(2+)` are occupied
C. pH of the solution decreases
D. Colourless `[Mg-EDTA ]^(2-)` chelate is formed

Answer

A

Explanation

`Mg^(2+)` forms an octahedral complex with EDTA A in which all six coordination sites are occupied by `Mg^(2+)` .
