Determining the Percentage Yield of Sodium Chloride produced from Sodium Bicarbonate Hydrochloric Acid

Introduction/Purpose:

Determination of the amount of sodium chloride produced from known quantities of sodium bicarbonate and hydrochloric acid. In the experiment, three trials were undertaken to determine the viability of the results. The purpose of the lab was to compare the experimental value with the theoretical value and calculate the percent yield to determine how much product was actually made compared with the amount of product that was expected.

Hypothesis: 

The percent yield will be high, because there would be little opportunity for mass to escape, providing the expected result of the product.

Material:

  • Sodium bicarbonate
  • Test tube rack
  • Bunsen burner
  • Electronic balance
  • Test tubes x 3
  • Sodium Chloride
  • Test tube clamp

Method:

At the beginning, a table has been made in order to record all the data. After the test tubes were numbered from one to three, they were weighted to 0.001 grams. Later, sodium bicarbonate was added to each test tube and they were again separately weighted. After that, the mass of sodium bicarbonate was measured in each tube. To begin the reaction, a drop of hydrochloric acid was added to each test tube separately. Then, the ...
