Question

When sodium bicarbonate and acetic acid are combined in a beaker and allowed to run to completion, a small amount of sodium bicarbonate remains unreacted at the bottom of the beaker at the end of the experiment. This means that the sodium bicarbonate is the _________ in this experiment.

Answer 1

Answer: Limiting Reactant!

Step-by-step explanation:

In this case, the sodium bicarbonate is the limiting reactant because it is the one that runs out first, leaving a small amount of it unreacted at the bottom of the beaker.
