General Chemistry I
Objective: In this experiment, we will predict a balanced equation for the reaction taking place, react to a known mass of NaHCO 3 with excess HCl, calculate the mole ratio between NaHCO 3 and NaCl., and determine whether your results support the Law of Conservation of Mass Results and Discussions: Table 1: shows the masses of measurements taken Mass (g) Calculations and observations Mass of glassware and watch glass 44.1428 g Mass of 𝑁𝑎𝐻𝐶𝑂 used 3 2.52 g 𝑁𝑎𝐻𝐶𝑂 is a white solid. When HCl was 3 added gas was released. Mass of glassware and watch glass & product 45.7668 g Mass of product 1.6240 g 45.7768g - 44.1428 g Post-lab Questions:
a. An excess amount of HCl was added to make sure there were enough moles of HCl. 2
