How do you prepare 1M sulfuric acid from concentrated sulfuric acid?

Answer 1

To prepare 1M sulphuric acid from concentrated sulphuric acid:

1. First consider the molecular weight of H2SO4 = 98 g/mol, so you have to add 98g of conc. acid and make up to 1 liter of water (as pointed out at the 4thpoint).
2. Considering that acid is a liquid, you should also consider density:

   where density = mass/volume, which is said on the bottle to be (about) 1.84 g/mL,

   so then you have: volume = 98g / 1.84(g/mL) = 53.2 mL

3. Now you have to consider the acid purity, usually 98% then you have to do this:

   53.2 mL if the acid were 100% pure convert in mL given with the purity of 98%, so 100% x 53.2 mL / 98% = 54.3 mL of (98%) concentrated acid.

4. Finally CAREFULLY add this 54.3 mL (or 98 g, cf. first point) to about 0.9 L dist. water while continuously stirring (evolving heat!), and after that fill it up to 1.00 L with also dist. water.

   Never reverse this: DO NOT add water to concentrated fluids!

Answer 3

The concentrated sulfuric acid should be diluted to prepare diluted sulfuric acid. The water should not be added directly as the tremendous heat would cause an explosion. Firstly, a desired amount of water should be added to a beaker of similar apparatus. Then it should be followed with the addition of the concentrated acid drop wise.

Answer 4

Pour 100 mL of concentrated hydrochloric acid (36,5 %) in 900 ml distilled water.

Answer 5

with the help of contact process....u can get more sulhpuric acid

Answer 6

By diluting the concentrated sulphuric acid accordingly.

Answer 7

By diluting the concentrated sulphuric acid with distilled water.
