A student tests a sample of iron(III) sulfate solution to confirm the presence of sulfate ions. They acidify the sample with dilute hydrochloric acid and then add barium chloride solution. A white precipitate of barium sulfate is formed.
One other product is formed in this precipitation reaction.
What is the chemical name of this other product?
barium hydroxide\text{barium hydroxide}barium hydroxide
iron(II) chloride\text{iron(II) chloride}iron(II) chloride
iron(III) chloride\text{iron(III) chloride}iron(III) chloride
hydrochloric acid\text{hydrochloric acid}hydrochloric acid
