CuO + H2SO4 \(\rightarrow\)CuSO4 + H2O
nCuO=\(\dfrac{1,6}{80}=0,02\left(mol\right)\)
nH2SO4=\(\dfrac{100.20\%}{98}=0,2\left(mol\right)\)
Vì 0,2>0,02 nên H2SO4 dư 0,18(mol)
Theo PTHH ta có:
nCuO=nCuSO4=0,02(mol)
C% dd CuSO4=\(\dfrac{0,02.160}{1,6+100}.100\%=3,15\%\)
C% dd H2SO4=\(\dfrac{98.0,18}{101,6}.100\%=17,36\%\)
