Preview - Stoichiometry - Creating A Fizzy Drink Part 1

Where did the bubbles come from?

In the last lesson, you watched while your instructor carbonated a beverage in front of you without a SodaStream.

Questions

Please answer the questions below.

1. If the total mass of the reactants (citric acid + sodium bicarbonate) in the weighing boats before the reaction took place was approximately 2.5 grams, estimate the mass of the total products in the beaker of water after the reaction took place.

2. Did your instructor cover the top of the products (the carbonated beverage) with a balloon or parafilm after mixing the reactants together? Think about how this may affect your answer to the previous question.
