Acid Content of Commercial Soda (5)
By: David Mulkey
1. An approximate weight of KHP was found in grams. Then three
measurements of KHP close to the approximate weight were found, and each
of the measurements was plugged into an equation for actual weight. These
answers gave the concentration of each approximate measurement in
molarity. The three molarities that were found were then averaged, and the
average was used in a given equation to determine the acid concentration of
the soda.
2. The calculations performed to determine the acid concentration in the soda
were based on the given equations on the board. The first equation gives the
approximate mass in grams of KHP that is needed in the next equation to
find the molarity of NaOH. The second equation uses the three actual
weights of KHP found that should be very close to the approximate weight
found in the first equation to find the molarity of NaOH. Then once these
answers are found the average of the three answers is used in the third
