mHCl=600*3.65/100=21.9(g)
mH2SO4=600*4.9/100=29.4(g)
nHCl=21.9/36.5=0.6(mol)
nH2SO4=29.4/98=0.3(mol)
Ta có các phương trình sau
6 HCl + 2 Al ➞ 2 AlCl3 + 3 H2
0.6..........0.2.............0.2........0.3(mol)
3 H2SO4 + 2 Al ➞ Al2(SO4)3 + 3 H2
0.3................0.2.............0.1...........0.3..(mol)
a=(0.2+0.2)*27=5.6(g)
m dung dịch X=600+5.6-(0.3+0.3)*2=604.4(g)
C%AlCl3=(133.5*0.2)/604.4*100%=4.418%
C%Al2(SO4)3=(0.1*342)/604.4*100%=5.659%
