Question
One of the key background concepts in this lab is the idea of limiting and excess
reactants.
Decide if each statements about limiting or excess reactants below is CORRECT or
INCORRECT.
Hint: To review this topic, you can read and practice in the course textbook section
Reaction Yields - Limiting Reagents.
✓
If there are initially more
grams of NaHCO3 than
grams of HCI in a flask, we
know that NaHCO3 must
be the excess reactant.
The amount of CO2 (g)
produced in each flask is
determined by the amount
of the limiting reactant
present in that flask.
If you knew that HCI (aq)
was the limiting reactant in
Flask C, you would then
know that HCI (aq) was also
the limiting reactant in
Flask B.
A reaction that has gone to
completion cannot have
any excess
reactant leftover.
1. CORRECT
2. INCORRECT
