How to make 78% concentrated h2s04 by adding 98% concentrated h2s04 to 56%concentrated h2so4
2 answers
hmmm. just keep adding it till the concentration rises to 78%
assuming the percents are by volume.
So assume you want XX ml of 78 percent ..
Va= concentrated stock at 56 percent
Vb= 98 percent stock in ml
.56Va+.98Vb=.78*xx
but Va+Vb=xxx
two equations, two unknowns
I get..
.98Vb-.56Vb= (.78-.56)xxx
or Vb=xxx*.22/.42= .52xx check that.
and Va= you do it.
and I probably would look at the fraction of Vb per unit of Va
