Question

4 You carry out the three classification reactions on your third unknown salt sample. You make the observations given below for each classification reaction lassification Rxn Observations Rxn with Ba (a) Addition of BaCl No observable change Rxn with Ag (aq) Addition of AgNO,-No observable change Rxn with H SO, (aq)Addition of H SO No observable change What possible anion(s) may be present in the third unknown salt sample? Describe the steps and expected observation(s) for the confirmation reaction for each anion identified as possibly present in the third unknown salt sample Name Date Previous Next Dashboard Calendar To Do Notifications Inbox

Explanation / Answer

Carbonate,sulphide,sulphite,nitrite react with H2SO4.Chlorides,bromides,Iodides,Nitrates react with conc. H2SO4.

SO42- and PO43- reacts with neither Conc.H2SO4 not dil.H2SO4.

It does not react with BaCl2, so the anion is not sulphite.

It does not react with AgNO3 so the anion is not chloride

so possible anion is SO42- and PO43-
