Standardization should be performed daily, since the titrant will absorb moisture over time. The standardization is typically performed using one of three standards (1) disodium tartrate dihydrate (15.66% water, w/w), (2) commercially available water standards with a certified concentration of water (typically, 10 mg of water per gram of standard), or (3) pure water. In all of these cases, a suitable balance should be used, preferably one that gives at least 0.1 mg of resolution. 

When disodium tartrate dihydrate is used, samples ranging from 50 to 120 mg are dissolved in methanol, and the concentration of the KF reagent is determined. Based on volume of titrant used, the weight of the sample and the percent water in the disodium tartrate dihydrate (15.66% w/w), the standardization factor can be calculated. One pitfall with this method is the solubility of the disodium tartrate dihydrate in methanol. It is recommended that the disodium tartrate dihydrate be finely divided and that a suitable extraction time be given for the solids to dissolve. 

Reaction of disodium tartrate with silver nitrate at pH S.6 was followed by the change in the absorption spectrum at 216-250 nm. Two complex ions were proposed, Ag(C4H4Oe)- and Ag(C4H406)2, with formation constants log j8i = 2.29 and log / 2 = 4.21 respectively.266... 

Sodium tartrate may be replaced with disodium tartrate, potassium sodium tartrate, or sodium citrate for better solubility.

Both (R,R) and (S,S) are diastereomers of (R,S) and (S,R). For disodium tartrate or for tartarie acid, there exists only one nonchiral mesoform instead of the enantiomers (R, S) and (S, R).
