Key Concepts and Summary A balanced chemical equation may be used to describe a reaction’s stoichiometry (the relationships between amounts of reactants and products). Coefficients from the equation are used to derive stoichiometric factors that subsequently may be used for computations relating reactant and product masses, molar amounts, and other quantitative properties.

The analysis of NaHCO3 in the tablet may not be affected by the high concentration of HCl solution, but the goal of observing the actions of limiting reactant will not be achieved. HCl solution with concentration ranging from 0.3 to 0.5 M is considered to be appropriate in this experiment. 7.

Introduction. Using a balanced chemical equation to calculate amounts of reactants and products is called stoichiometry. It is a super technical-sounding word that simply means using ratios from the balanced equation. In this article, we will discuss how to use mole ratios to calculate the amount of reactants needed for a reaction.

Jan 03, 2012  · Weigh the antacid tablet. Grind the tablet and put all the powdered material into a beaker. Dissolve this in approximately 200mL of 0.1M HCl acid. The solution may contain a small amount of undissolved, unreactive residue but this does not interfere with the analysis.

Antacid Calcium Carbonate 500 Mg Chemistry 104: Analysis of Commercial Antacid Tablets. Hydrochloric acid (HCl) is one of the substances found in gastric juices secreted by the lining of the stomach. HCl is needed by the enzyme pepsin to catalyze the digestion of proteins in the food we eat. Calcium carbonate is a dietary supplement used when the amount of

The amount of NaOH needed to completely neutralize the HCl is the amount of HCl that did not react with the acid. This is because the neutralization reaction that occurs involves a 1:1 stoichiometric ratio of HCl to NaOH, so the moles of NaOH added is equal to the amount of HCl left in solution.
