How do you make 0.02N sulfuric acid solution?

Answer 1

I would like to dilute some 5N sulfuric acid with water, and make 0.1N sulfuric acid solution. I want 1000ml of 0.1N . I think it's a 50 to 1 ration, but just want to make sure.

<Volume of concentrated> x <Concentration of Concentrated> =

<Volume of dilute> x <Concentration of dilute>

Therefore,

<Volume of concentrated> =

<Volume of dilute> x <Concentration of dilute> / <Concentration of dilute> =

1000 mL x 0.1 N / 5N = 20 mL.

Meaning: Dilute 20 mL of the 5N H2SO4 to 1000 mL in a volumetetric flask will give you 1000 mLs of 0.1 N H2SO4 (aq.).

Answer 2

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 = 1N

Now, N/50 = 27.2/50 =0.543 ml

Therefor, TAKE O.543 ML OF SULPHURIC ACID AND MAKE FINAL VOLUME TO ONE LITRE which will give you 0.02N H2SO4 solution

Answer 3

Simply dilute 1N sulphuric acid hundred times by adding water e.g.If we want to make 100ml of 0.01N sulphuric acid from 1N sulphuric acid then take 1ml of 1N sulphuric acid and make the total volume equal to 100ml.

Answer 4

If you mean 0.25 m, as in 0.25 molal, then you need 0.25 moles of H2SO4 in a total of of 1 kg of solvent. For 100 ml, using water and assuming a density of 1g/ml, then 0.25 mol/kg x 0.1 kg = 0.025 moles H2SO4. And 0.025 moles H2SO4 x 98 g/mole = 2.45 g H2SO4. If, on the other hand, you mean 0.25 M, as in 0.25 molar, then you need 0.25 moles H2SO4/liter x 0.1 L = 0.025 moles = 2.45 g H2SO4. So, in one case you add 2.45 g H2SO4 to 100 ml H2O to make 0.25 m, and in the other case you add 2.45 g H2SO4 to enough H2O to make a final volume of 100 ml to make 0.25 M.

Answer 5

To make a 0.02N sulfuric acid solution, you would need to dilute a concentrated sulfuric acid solution to the desired concentration by adding the appropriate amount of water. Calculate the volume of concentrated sulfuric acid needed based on its known concentration and desired final volume of the solution. Finally, dilute the calculated amount of concentrated sulfuric acid with water to reach the desired 0.02N concentration.

Answer 6

Add slowly to 1020 mL of water 3.0 mL of conc sulfuric acid. This will give you 0.1 N Sulfuric Acid.

Answer 7

Take 100 ml of 1N H2SO4 and then dilute it or make up to 1000ml in a volumetric flask that will give 0.1 N H2SO4.

Answer 8

first make 10N solution by addind 27.7ml conc H2So4 in 73.3ml water then take 1 ml from 10N and add 999ml water

Answer 9

1.12 ml H2SO4 of specific gravity 1.834 - 1.836 in 1 litre of distilled water.
