Which reagent would enable you to remove

\mathrm{SO}_4^{2 - }

ions from solution containing both

\mathrm{SO}_4^{2 - }

and

\mathrm{C}{\mathrm{l}^ - }

ions?

View answer and explanation

Correct option: C

\mathrm{Ba}{\left( {\mathrm{OH}} \right)_2}

Option C is correct because

Ba(OH)_2

will precipitate

SO_4^{2-}

ions as

BaSO_4

, which is insoluble, while not reacting with

Cl^-

ions.
