The limiting reactant, is the reactant that forms the less amount of product.
Balanced equation: 3 NaHCO3(aq) + H3C6H5O7(aq) → 3 CO2(g) + 3 H2O(l) + Na3C6H5O7(aq)
Mole to mole comparison:
The fizz produced when an Alka-Seltzer® tablet is dissolved in water is due to the reaction between sodium bicarbonate (NaHCO3) and citric acid (H3C6H5O7): 3 NaHCO3(aq) + H3C6H5O7(aq) → 3 CO2(g) + 3 H2O(l) + Na3C6H5O7 (aq). In a certain experiment 1.30 g of sodium bicarbonate and 1.30 g of citric acid are allowed to react.
How many grams of the excess reactant remain after the limiting reactant is completely consumed?
