98.4 ml of Methanol + 0.3 ml Ammonium Hydroxide + 0.4 ml EBT + 0.8 ml Water.
Some NaCl needs to be added to make the indicator more stable but I am not aware of the proportions. As far as I know the formula above should suffice.

What is role of eriochrome black t in zn-edta titrations?
The indicator added to the sample is Eriochrome Black T. Initially, the indicator will form a complex with the cations. When complexed it is red in color. As the EDTA is added dropwise to the sample, it replaces the Erio T and forms more stable complexes with calcium and magnesium. When the indicator is released by the metal ions, it has a distinct blue color. Therefore, the endpoint of the titration is marked by the color change form red to blue
