What is POTASSIUM HEXAHYDROXOANTIMONATE(V)?
The Uses of POTASSIUM HEXAHYDROXOANTIMONATE(V)
Potassium antimonyl trihydrate is used as a detecting agent for sodium. It is used as a mordant/ fixing agent in leather and textile dying industries. It is also used as a analytical reagent and flux additive for electroplating.
What are the applications of Application
Potassium hexahydroxoantimonate(V) is an antimony compound used to detect sodium (precipitation)
Preparation
Heating antimony pentoxide with excess potassium hydroxide produces rubbery, granular, or crystalline products. If the substance is recrystallized from a little water, deliquescent mammilated crystals form. Treated with copious cold water or boiled together with a small quantity of water, they are converted into potassium hexahydroxyantimonate, K[Sb(OH)6], which is sparingly soluble in cold water but somewhat more soluble in warm water. Solutions precipitate sodium as the sparingly soluble sodium hexahydroxyantimonate, Na[Sb(OH)6]. This reaction is used for the detection of sodium.
