由题意：
H2SO4+BaCl2==BaSO4↓+2HCl
1moL 233g 2moL
n(H2SO4) 9.32g n1
n(H2SO4)=9.32*1mol/233g=0.04moL (2)
n1=9.32*2mol/233g=0.08moL (1)
滤液中HCl的总量为
HCl+NaOH==NaCl+H2O
1moL 1moL
n2 4moL/L×35/1000L
n2=[4mol/l*(35/1000)L*1mol]/1mol=0.14moL (2)
原溶液中HCl物质的量
n(HCl)=n2-n1
=0.14moL-0.08moL
=0.06moL (2)
原溶液中：
C（H2SO4）＝(0.04mol/100)/1000L＝0.4moL/L (1)
C(HCl)=(0.06mol/100)/1000L =0.6mol/L (2)
