Question

63. When 120 reacts with 50 litre sample of CO gas,
the CO gas converted into co, according to given
reaction,
120(s) + 5CO(g) → 5CO2(g) + 12(9)
The iodine distilled at this temperature and was
collected in an absorber containing 10 ml of 0.025
molar Na, S2O3. The excess hypo was back titrated
with 10 ml of 0.002 molar I, solution. Then it is found
that mass of 205 (solid) used for the reaction of
sample of 50 litre of CO gas is a < 10-3 gram. Then
value of 2a is (molar mass of I, is 254 g/mol)​

Answer 1

Answer:

63. When 120 reacts with 50 litre sample of CO gas,

the CO gas converted into co, according to given

reaction,

120(s) + 5CO(g) → 5CO2(g) + 12(9)

The iodine distilled at this temperature and was

collected in an absorber containing 10 ml of 0.025

molar Na, S2O3. The excess hypo was back titrated

with 10 ml of 0.002 molar I, solution. Then it is found

that mass of 205 (solid) used for the reaction of

sample of 50 litre of CO gas is a < 10-3 gram. Then,,,,__

value of 2a is (molar mass of I, is 254 g/mol
