Using this equation for the reaction of sodium bicarbonate with HCl answer the
following.
NaHCO3 (s) + HCl (aq) ------> NaCl (s) + H2O (g) + CO2 (g)
a. How many moles of sodium bicarbonate are needed to make one mole of NaCl?
b. What was the purpose of heating/drying during this experiment?
c. You discover that your experimental yield is higher than the theoretical yield
you calculated, what is the most likely cause?
d. Why must the HCl be added slowly in this reaction?
e. Why should you not set the hot plate too high in this reaction?
f. Why did you need to weigh the product multiple times?
g. You determine that the weight of the casserole with your massed sodium
bicarbonate is 33. 392 grams, given that the original mass of the casserole
was 30. 482 grams, how much sodium bicarbonate did you weigh out?
h. Using this value, what is the theoretical yield of NaCl that can be obtained
given that the molecular weight of NaCl is 58. 44 grams/mole and the
molecular weight of sodium bicarbonate is 84. 0 grams/mole?
i. How much water is expected to be produced given that water weighs 18. 0
grams/mole?
j. What states are possible for the water that is produced?
k. You find that you have obtained 2. 594 grams of NaCl, calculate the percent
yield.
