The following data were obtained as averages of two trials each for two different unknown antacids utilized in the experiment presented in this lab. Remember, the procedure for this lab is identical to the technique used for the titration/Volumetric Analysis lab. Only, we have added the impact of an acid neutralizing antacid to each experiment trial.
Just looking at the data, which antacid do you think is the better one? Why? (note: the points from this question will be the justification behind the why moreso than whether or not you chose the correct antacid. So this one can be answered based on the background readings, and does not require the lab to have been completed prior.)
Unknown antacid A:
mass flask : 0.000 g
mass flask + sample: 0.260 g
Total volume HCl: 10.00 mL
Molar conc HCl: 0.109 M
Molar conc NaOH 0.105 M
init buret reading: 0.00 mL
final buret reading: 6.45 mL
_______________________________________________________
Unknown antacid B:
mass flask + sample: 0.252 g
init buret reading: 0.00 mL
final buret reading: 4.94 mL
(note: numbers in data set A that are not presented in data set B are constant values, so should be carried across to the second calculation)

The following data was obtained from two independent samples for
which sigma was unknown; they were selected from two normally
distributed populations.
Sample 1: 27, 39, 25, 33, 21, 35, 30, 26, 25, 31, 35, 30, 28

The following data were obtained from experiments to find the
molecular formula of an unknown compound which acts as a common
local anesthetic. The unknown compound contains only carbon,
hydrogen, nitrogen, and oxygen. Complete combustion of a 4.82 g
sample of the unknown compound with excess oxygen formed 12.67 g of
carbon dioxide and 4.076 g of water. Another sample of the unknown
compound with a mass of 1.12 g was found to contain 0.1339 g of
nitrogen. The molar...

The following data were obtained in a study using three separate
samples to compare three different treatments. Conduct an analysis
of variance with α=0.05α=0.05 to determine whether these data are
sufficient to conclude that there are significant differences
between the treatments.
