Question

0.3660g of a metallic sulphide was roasted in air to yield the oxide of the metal along with SO2 which was passed into bromine water the solution was boiled cooled and treated with barium chloride solution 0.875g of BaSO4 was obtained calculate the equivalent weight of the metal (ba=137.4)

Answer 1

the ans=~32.8 plz solve it

Answer 2

@Kryten plz help

Answer 3

can someone help me plzz

Answer 4

are you 100% sure the right answer is 32.8 ?

Answer 5

yes the ans is ~32.8

Answer 6

32.8 represents the molecular weight of the metal, so your metallic sulphide is one of these: CdS, PbS, MoS2, Na2S, ZnS, SeS2, FeS2, but none of those metals has a molecular weight of 32.8...

Answer 7

it is asked to find the equivalent weight
