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

Options

A. Four coordinate sites of `Mg^(2+)` are occupied by EDTA and remaining two sites are occupied by water molecules
B. All six coordinate sites of `Mg^(2+)` are occupied
C. pH of the solution is decreased
D. Colourless `[Mg-EDTA]^(2-)` chelate is formed

Answer

A

Explanation

`Mg^(2+)` forms an octahedral complex with EDTA where all six coordinate sites of `Mg^(2+)` are occupied.
