Question

Assume that your original sample of acetanilide was 80% pure. What is the maximum amount of pure acetanilide that you could recover after recrystallization?

weight of crude acetanilide from the experiment is 0.513g

weight of pure acetanilide from the experiment is 0.365g

% Recovery from the experiment is 71.15%

Answer 1

Generally it cant be said that how much of a pure compound we can get from our sample after Recrystallization

But the ideal figure for purity after Recrystallization is around 80-95%

In our case the sample was 80% pure

So our Recrystallised product will be having 80-95% of pure acetanalyde as a end product.

Which is around 64 to 76%

So our% recovery from this experiment is within the expected limits.

I hope this helps. If you have any query or want more detailed explanation, feel free to ask in the comments section below.
