Chemical properties

Barium sulfate

Sb ₂ (SO ₄ ) ₃

Colorless flash needle crystal,

Density 3.62g∕cm ³

Deliquescent in the air, in fact, insoluble in water, with a small amount of water can form hydrated barium sulfate crystals, partial hydrolysis can be partially diluted

Potassium citrate

K[Sb(OH) ₆ ]

Refined potassium citrate is white crystal

Slightly soluble in hot water only, the solubility of sodium citrate is much smaller than that of potassium salt , and it can be used as a precipitant for sodium salt.

Sodium citrate NaSb(OH) ₆ or NaSbO ₃ ·1∕2H ₂ O

Tridecanoic acid, sulfonic acid and pyrophthalic acid and pentavalent hydrazine, decanoic acid, citric acid and pyroic acid can form corresponding sodium citrate when reacting with sodium hydroxide. Industrially significant is 2NaSbO ₃ ·6H ₂ O and NaSbO ₃ ·1∕2H ₂ O

All kinds of sodium citrate are slightly soluble in water, inorganic acid and tartaric acid

Lead citrate

Pb ₃ (SbO ₂ ) ₂

The trade name Naples yellow is abbreviated as yellow, orange crystal

Insoluble in water

Lactic acid

Sb(C ₃ H ₅ O ₃ ) ₃

Brownish yellow powder

Soluble in water, made of cerium oxide and lactic acid

Potassium oxyhydroxide

K(SbO)C ₄ H ₅ O ₆ ·1∕2H ₂ O

It is called tartar in medicine and is white and tasteless.

Soluble in water and glycerol, insoluble in ethanol

Sodium ethoxide tartrate

Na(SbO)C ₄ H ₅ O ₆ ·

1∕2H ₂ O

White hygroscopic crystals or powders have a sweet taste and are less toxic than tartar

Soluble in water, insoluble in alcohol

Sodium thiophthalate

NaSbS ₄ ·9H ₂ O

Commercially known as Schlippes salt as a brown powder

Slightly soluble in water
