问题详情

A 100mL portion of a 0.1000mol·L-1 aqueous solution of the weak acid HA is extracted with 50.00mL of CCl4. After the extraction,a 25.00mL aliquot of the aqueous phase was titrated with 10.00mL of a 0.1000mol·L-1 NaOH. Calculate the distribution ratio of HA.

参考答案

ntotal=0.1000mol·L-1×100mL=10.0mmol
nw=0.1000mol·L-1×10.00mL×4=4.000mmol
no=ntotal-nw=10.00mmol-4.000mmol=6.00mmol
So
