Question

An unknown solution is determined to contain either silver nitrate (AgNO3) or barium nitrate (Ba(NO3)2. Using a precipitation reaction, how could you identify the unknown? Specificy which ion you would add to the unkown and how the results would identify which compound is in the unknown.

Explanation / Answer

add Na2SO4 to the reaction of precipitate forms then Ba(NO3)2 is present as BaSO4 is insoluble in water

if no precipitate AgNO3 is present
