The fizz produced when a Alka-Seltzer tablet is dissolved in water is due to the reaction between sodium bicarbonate(NaHCO3) and citric acid(H3C6H5O7): 3NaHCO3(aq) + H3C6H5O7(aq) --> 3CO2(g) +3H2O(l)+Na3C6H5O7(aq) In a certain experiment 1.30g of sodium bicarbonate and 1.30g of citric acid are allowed to react.
