Answer:

Explanation:

For the answer to the question above,

Addition of HCl causes a precipitate to form:

Ag+ & Cl- -- AgCl a white ppt

H2SO4 is added to the supernate another precipitate forms:

Ba+2 & SO4-2 --> BaSO4 a white ppt

a solution of NaOH is added to the supernatant liquid until it is strongly alkaline. No precipitate is formed:

no Mn+2 & no Cu+2 which would have ppt as hydroxides

I hope this helps you.
