DST is primary standard and it is stable up to 150 degree Centigrade. It release free water molecules easily when reacts with KF reagent.DST is easily soluble in methanol. This DST has 15.66% water molecules so we can easily calculate and standardize the KF reagent. We use the factorof DST the compound which has less … Continue reading Why only Water & Sodium Tatrate Is Use For Calibration Of Karl Fischer Titrator?
