Is your zincate a solid or a solution?

zincate solution:

Do a reverse titration. It is assumed, that your zincate solution (analyte) is added to your iodine stock solution in THF (titrant).

Equivalents of I₂:

Measured mass of I₂: mg

Used volume of zincate: mL

Total volume of zincate: mL (not required)

zincate solid (in the works):

Grignard (or phenyl lithium) titration calculator

For the titration of Grignard reagents (or sometimes phenyl lithium), salicylaldehyde phenylhydrazone (Love's reagent) can be used as an indicator. The original paper by Love and Jones can be found here: J. Org. Chem. 1999, 64, 3755–3756.

Equivalents of Love's reagent:

Measured mass of Love's reagent: mg

Used volume of Grignard solution: mL

Total volume of Grignard solution: mL (not required)

Lithium organyls (e. g. (n-/s-/t-)BuLi)

For the titration of organolithium reagents, N-pivaloyl-o-toluidine or N-pivaloyl-o-benzylaniline (Suffert's reagent) can be used as an indicator. The original paper by Jean Suffert can be found here: J. Org. Chem. 1989, 54, 2, 509–510
