Potassium oxalate

chemical substances
oxalate Potassium is an organic sylvite , the molecular formula is K two C two O four Nature and hydrate Similar, with reducibility. Saturated solution yes Weak alkalinity It is highly corrosive and can cause congestion and erosion of digestive tract [1] By setting Potassium carbonate Put into hot oxalic acid solution until the solution Phenolphthalein When it is weakly alkaline, it crystallizes Potassium oxalate monohydrate , and then heated to 160 ℃ for dehydration Opaque And get. Can be used as Analytical reagent , prevent Blood coagulation , also for Pharmaceutical industry And film development [2]
