Dear Student
Imagine this with me ..
if you added water to , Sodium Chloride , which is ( table salt ) , Sodium
Chloride will dissolve in water .

And to filter means :adding water to the mixture then add the mixture to a filter paper so materials that do not dissolve in water will remain in the
filter paper .
So sodium chloride will not remain in the filter paper , because it is
already dissolved in water ,

So we can not use filtration to separate sodium chloride in water.
