Percentage Yield Flashcards
1
Q
What is the yield
A
The mass of useful product abstained from a reaction
2
Q
How do you calculate the percentage yield
A
( Actual yield / theoretical yield ) * 100
3
Q
Why is the yield less than expected give 3 reasons
A
Some product may be lost when it’s separated from the reaction mixture (traces left in beaker)
Some reactants may react in different ways from the expected reaction
The reaction may not go to completion because it’s reversible (product can change back)
