To make 0.02 N of H2SO4 what is the procedure?

Answer 1

N is strength in gms/lit

For 0.02N H2SO4

u need 0.02 gms of H2SO4 per litre of water solution.

And 0.02 gms = (0.02/ density H2so4 )volume

So add found out V ml H2SO4 to 1 litre of water.

Answer 2

Use the formula:

W =desired volume X desired Normality X EW(equivalent weight)

W = 1 liter X 0.02 N X 98/2 (EW = MW/valence)

W = 0.98 H2SO4 g/L

Weigh 0.98 grams of H2SO4 and then diluted to1 liter of distilled water.
This will give you 0.02 N of H2SO4

Answer 3

Well, the normality (N) of a solution is actually the number of equivalent masses per Litre of solution.
The equivalent mass is the molecular mass divided by the number of reacting species per molecule.
For an acid, such as sulphuric acid (H2SO4), the reacting species is H+, so the number of reacting species per molecule is 2 as ther are 2 H atoms per H2SO4 molecule.
Therefore the equivalent mass of sulphuric acid is 98.1 / 2 = 49.05g

To make one litre of 0.02N solution you would need 0.02 equivalent masses, which is 0.02 x 49.05 = 0.981g of H2SO4.
Concentrated sulphuric acid is commonly 98% H2SO4 by weight, so you could weigh out 1.001g of concentrated acid (1.001g x 98% = 0.981g of H2SO4), and dilute it to 1 Litre in a volumetric flask

Answer 4

Any molarity (suppose xM) of H2SO4 can be prepared by simply prepared by 54*x in equal volume of water and then diluted upto 1000 ml.

Answer 5

Eq wt x 100/% purity x specific gravity = 49x1000/98x1.84 =27.2 so take 27.2 ml
h2so4 and make final volume to one litre = 1NNow, N/50 = 27.2/50 =0.543
mlTherefor, TAKE O.543 ML OF SULPHURIC ACID AND MAKE FINAL VOLUME TO ONE LITRE
which will give you 0.02N H2SO4 solution.

Answer 6

take 0.56 ml from cnonc h2so4 and add to 1 liter of distilled water

Answer 7

Use the formula, Normality = Mass of substance in 1l of sol./ Equivalent mass

Answer 8

add 0.543 to L distilled water

Answer 9

Let it dry up?
