A water supply has been contaminated with

an unknown mixture of toxic metal solutions

leaking from a nearby factory. One way to treat

the problem is to precipitate the metals from the

water. Environmental chemists are considering

using sodium carbonate and sodium sulfate for

this purpose. Based on the solubility table, which

compound would you recommend?

Know the Answer?

Angela Juarez · Answer 1

According to the provided table of solubility the metals that form a precipitate with carbonate and sulfate are Ba and Pb but the only toxic one of these two metals will be Pb (lead)

Jaqueline Hooper · Answer 2

Metals which are from precipitate with sulfate and carbonate are barium and Lead.

The only toxic of these metals is lead. Lead is heavy metal which is denser with most common materials.

It contains major decay chain which has heavier elements. It is unreactive post-transition metal.
