In KF Standardisation Why We using Disodium Tartarate?

Answer Posted / rajesh jaiswal

We can also use distilled water instead of DST, but we can not take water weight, hence DST is used.

During analysis, Ist methanol will take and neutralize moisture in methanol with some amount of KF & after that add DST & the water availability should be 15.6%.

DST is more stable
Very soluble in methanol
Two mol of hydrate stable
stable at 105 c
we can take wt
