Cu +2H₂SO₄concentrat =CuSO₄+SO₂ + 2H₂O
MCu =64g
MH₂SO₄ =(2*1)+ 32+(4*16)=34+64=98g
64g Cu ....................................98g H₂SO₄
128g Cu......................................x
x= (128*98) ÷64 =196g H₂SO₄
md = 196 g H₂SO₄
c=90%
ms=?
c= (md *100)/ms
ms = (md*100)/c
ms=(196*100)/90=217,77g solutie
