Earlier in the course, you characterized the ability of powders to adsorb arsenic from water. Another approach to arsenic remediation is to use a reaction that forms a solid compound with the arsenic. The solid will precipitate from the water and remove the arsenic. In these cases, it's important to know what remains in the solution after the precipitation since both reactants (the arsenic and the compound you are using to precipitate it) may be undesirable.
One of the proposed reactions is:
Your goal here is to determine what is left over when we mix a diluted solution that contains (click here if you want step-by-step help to solve this problem)
