Chemistry: Reaction between Sodium Bicarbonate and Citric Acid
Question: The fizz produced when an Alka Seltzer© tablet is dissolved in water is due to the reaction between sodium bicarbonate and citric acid, according to the following equation:
3NaHCO3(aq) + H3C6H5O7(aq) -> 3CO2(g) + 3H2O(l) + Na3C6H5O7(aq)
In a certain experiment, 1.00 g of sodium bicarbonate and 1.00 g citric acid are allowed to react.
- Which is the limiting reactant?
- How many grams of carbon dioxide are formed?
= How many grams of excess reagent remain after the limiting reactant is completely consumed?
