We have 4 test tubes filled with aqueous solution, one of which is definitely yellow. Use the information below to determine the composition of the solutions. Give the name of the cation and anion of the compunds! (there will be 4) Upon pooling of the contents of tubes 1 and 2, a white precipitate is formed which dissolves not in nitric acid but in ammonia. A yellow precipitate forms when the contents of tubes 1 and 3 are combined. When the contents of tubes 1 and 4 were combined, a brown precipitate formed. The solution turns brown when the contents of tubes 2 and 3 are combined. A yellow precipitate forms when the contents of tubes 1 and 3 are combined. When the contents of tubes 2 and 4 were combined, a reddish-brown, gelatinous precipitate formed which did not dissolve in excess reagent. No change is made when the contents of tubes 3 and 4 are pooled. Aqueous solutions of some tubes give a positive reaction to potassium and nitrate ions and must not contain sodium ions.
