Bleaching powder and bleach solution are produced on a large scale and used in several household products. The affectiveness of bleach solution is often measured by iodometry.
25 ml of household bleach solution is

A

0.48 M

B

0.96 M

C

0.24 M

D

0.024 M

Text Solution

Verified by Experts

The correct Answer is:
C
`eq_(I_(2))=eq_(Na_(2)CO_(3))=eq_(Cl_(2))`
`eq_(Cl_(2))` liberated = `(4.8)/(1000)xx0.25`
`therefore` moles of `Cl_(2)=(48xx0.25)/(1000xx2)`
`therefore` moles of bleaching powder = `6xx10^(-3)`
`therefore` Molarity = `(6xx10^(-3))/(0.025)=0.24M`
