BiAsO4
The chemical formula BiAsO4 corresponds to the compound Bismuth arsenate.
The chemical formula of chromium(III) arsenate is CrAsO4.
The chemical formula for Bismuth III phosphate is BiPO4.
PAsO4
BiI3
The formula for bismuth (III) telluride is Bi2Te3. It is composed of bismuth ions with a +3 charge and tellurium ions with a -2 charge in a 2:3 ratio.
The chemical formula of bismuth III perchlorate is Bi(ClO4)3. It consists of one bismuth (Bi) ion and three perchlorate (ClO4-) ions.
The chemical formula for the compound formed between bismuth (III) and bromine is BiBr3. This compound is formed when bismuth, which has a +3 oxidation state, reacts with bromine, which has an oxidation state of -1.
bismuth(III)sulfide
When arsenic reacts with iron(III) hydroxide, it forms iron(III) arsenate and water as the products. This reaction is a precipitation reaction, where a solid precipitate of iron(III) arsenate is formed.
FeAsO3 is the chemical formula of the iron (III) arsenite.
That would be chromium(II) sulfate, but really, chromium mostly exists as Cr(III) or Cr(VI), which would change the formula.
