Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
In this question both Assertion and Reason
are correct however Reason is not the
correct explanation for Assertion as from
the solution it is clear that strength of
H2O2 is just a term to express conc. of H2O2
in terms of volumes of oxygen gas based
on its decomposition to from water and
oxygen. This has nothing to do with normality
2H2+O22H2O+O2
Lets say we have M moles H2O2 in
1L solution.
from the given reaction
2 moles H2O2 gives 1 mol of O2 i.e 22.4m
1 mole of H2O2 gives (11.2×M)L of O2
1L of H2O2 gives (11.2×M)L of O2
Volume of H2O2=11.2×M
n factor of H2O2 is 2
Now,
Normality = Morality × n factor
N=M×2
M=N2...(1)
Volume M×11.2
Strength 11.2×N2....(2)
