Barium Chloride Test
Barium Chloride Test is used to determine the presence of Sulphur in HCl extract of Plant Ash.
Principle:
Barium Chloride performs double displacement reactions i.e.ionic reaction.
Experiment | Observation | Inference |
To about 5-10 ml of HCl extract of Plant Ash , a few drops of 5% BaCl2 is added. | A white crystalline ppt. is formed. | Presence of Sulphur is indicated in the Ash extract. |
Reactions:-
X2 SO4 (aq)+ BaCl2(aq) →BaSO4(white ppt) + 2 XCl(aq)
