He was also the first to recommend starch as a reagent for free iodine and he studied chemistry of arsine and bismuthate salts.

Lead bismuthate forms a pentavalent structure, significantly different from the regular ionic interactions of sodium bismuthate, but similar to that of strontium bismuthate.

However, lead bismuthate is not as effective at decomposing organic matter as other metal oxides or bismuthates due to its broad valence band and small band gap.
16.
Direct precipitation of sodium salts from aqueous solutions is rare because sodium salts typically have a high affinity for water; an exception is sodium bismuthate ( NaBiO 3 ).
17.
Permanganate salts can also be generated by treating a solution of Mn 2 + ions with strong oxidants such as lead dioxide ( PbO 2 ), sodium bismuthate ( NaBiO 3 ), or peroxydisulphate.

Gastric cytoprotective drugs include carbenoxolone, deglycyrrhizinised liquorice, sucralfate ( aluminium hydroxide and sulphated sucrose ), misoprostol ( a prostaglandin analogue ) and bismuth chelate ( tri-potassium di-citrato bismuthate ).

Specifically, research has shown that if sufficient amounts of barium and zinc oxides are used simultaneously for the stabilization of lead bismuthate glasses, the decrease in the infrared transmission becomes insignificant compared to the stability of the glass.

The oxide, Bi 2 O 3 is predominantly basic but will act as a weak acid in warm, very concentrated KOH . It can also be fused with potassium hydroxide in air, resulting in a brown mass of potassium bismuthate.
