Coys4ever Posted April 25, 2017 Share Posted April 25, 2017 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 ? Link to comment Share on other sites More sharing options...
hypervalent_iodine Posted April 25, 2017 Share Posted April 25, 2017 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). Link to comment Share on other sites More sharing options...
Itoero Posted April 25, 2017 Share Posted April 25, 2017 Yes, don't forget to add the acid to the water! Link to comment Share on other sites More sharing options...

Elite Engineer Posted April 28, 2017 Share Posted April 28, 2017 (edited) 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.

Country Boy Posted May 3, 2017 Share Posted May 3, 2017 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.

Itoero Posted May 4, 2017 Share Posted May 4, 2017 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. Link to comment Share on other sites More sharing options...
hypervalent_iodine Posted May 4, 2017 Share Posted May 4, 2017 It's really just because otherwise things get too hot and fumey, as EE says. No need to over complicate it. Link to comment Share on other sites More sharing options...
