Question

The normality of 10 ml of a 20 V H2O2 solution is ?

Answer 1

@ParthKohli

Answer 2

do u know what's 20 V H2O2 ?

Answer 3

20 M H2O2? Not sure what 20 V is...

Maybe volume/volume percentage?

Answer 4

ok..wiat !

Answer 5

so that means that 20 ml of H2O2 in 100 ml of solution..ryt ?

Answer 6

If V means %V/V, then sure.

Answer 7

ok let us suppose it is %v/v ....then how to proceed towards Normality ?

Answer 8

How to do that without any density given ?

Answer 9

Not sure how...

Answer 10

Density is required. Without that, not sure at all.

Answer 11

What if it is 20 molar H2O2 solution?

Answer 12

then it means that 20 moles in 1 litre

Answer 13

20 moles=34*20=680 g

Answer 14

Normality = Molarity * n-factor

Answer 15

yes..what will be the n factor here ?

Answer 16

@Abmon98 what do u think ?

Answer 17

I'm sorry, I haven't really studied this outside acids and bases.

I'm Googling to see what the n-factor is in these cases.

Answer 18

oh i see..it's ok...thanx for the concern buddy !

Answer 19

btw the answer is 3.58

Answer 21

Normality of a solution is defined as the number of gram equivalents of the solute dissolved per litre (dm3) of given solution.
is V the volume of solution?

Answer 22

But the volume is already given as 10 ml, so it has to be something that's not the volume.

Answer 23

20 volume means 1dm3 of the H2O2 solution will produce 20dm3 of oxygen, where:

H2O2 -> O2 + H2:

i.e 1:1 stoichiometry. At 298K and 1atm pressure, 1 mole of gas occupies 24.45dm3. So 20/24.45 = 0.818 mol. O2 produced, which means there were 0.818mol H2O2 in 1dm3. Therefore molarity is 0.818M at 298K.
