PTHH: Al2O3+6HCl➝2AlCl3+3H2O(1)
a)nAl2O3=\(\dfrac{10,2}{102}\)=0,1(mol)
mHCl=\(\dfrac{5\%.219}{100\%}\)=10,95(g)
⇒nHCl=\(\dfrac{10,95}{36,5}\)=0,3(mol)
Xét tỉ lệ Al2O3:\(\dfrac{0,1}{1}\)=0,1
Xét tỉ lệ HCl:\(\dfrac{0,3}{6}\)=0,05
⇒HCl pứng hết,Al2O3 còn dư
Theo PTHH(1) ta có nAl2O3 pứng=\(\dfrac{nHCl}{6}\)=\(\dfrac{0,3}{6}\)=0,05(mol)
⇒nAl2O3 dư=nAl2O3ban đầu-nAl2O3 pứng=0,1-0,05=0,05(mol)
⇒mAl2O3 dư=0,05.102=5,1(g)
b) C%HCl=\(\dfrac{0,3.36,5}{219+10,2}\).100%=4,8%
nAlCl3=0,1(mol)
⇒C%AlCl3=\(\dfrac{0,1.136,5}{10,2+219}\).100%=6%
