Hello students welcome here in this question they are asking that after recrystallization what affects thus the presence of any impurity have on yield so if any impurities are present in a compound so after recrystallization what will be the effect on yield impurities effect so effect on yield is so we know that recrystallization is a process of purification method it is.
00:33
So if there are any impurities present in the compound, then the yield will be yield.
00:45
Percentage of yield, if some yield decreases.
00:50
So percentage of yield decreases, okay? so that is the effect of presence of impurities after recrestralization.
01:00
And the second question asking that, when after a neighboring group recrystallized a pure compound and achieved only 20 % of recovery, give two likely reasons for their result for each cause what could be done.
01:20
So to improve the outcome.
01:23
So we know that it is only 20 % recovery.
01:27
So what is the reasons for this one is? still some solute.
01:32
So solute is present in dissolved form...
