10% H2SO4

[Coys4ever]

Hi

 

I need to make a 10% solution of cons H2SO4. I need 2000ml

 

Is this the right formula

 

2000ml x 10% = xml x 98% H2SO4

 

xml = 20000/98% = 204ml H2SO4 ?

Yep, that's about right. Just remember to take extreme caution using conc H2SO4, and add the acid to the water (never the other way around).

Yes, don't forget to add the acid to the water!

Thanks:)

Incase people are wondering why you add ACID to the WATER is because you want a heat sink when the acid is mixed with the water plus whatever else is in it.

It is ​because​ if you add a little water to a lot of acid, there will be a lot of spattering that is mostly acid and so very dangerous. adding a little acid to a lot of water immediately dilutes the acid.

H2O is almost 2 times less dense then H2SO4. So the H2SO4 drops immediately bellow the water which dilutes the H2SO4 and the ionization happens bellow the water while it gets diluted.

It's really just because otherwise things get too hot and fumey, as EE says.

No need to over complicate it.
