Question

Answer these questions please!
1- Why Components in a mixture can be seperated by phisical methods only.
2-Why a filter paper is moistened before fitting it it into a funnel for any experiment?​

Answer 1

Answer:

1. Components in a mixture are not chemically mixed so we cannot separate them by chemical means so we have to separate it by physicals means

2.The reason one needs to wet the filter paper is not only to allow adhesion of it to the funnel but also to facilitate the solute to easily percolate through its pores without wetting it ( this is true for both organic and aqueous solvents).
