Safety:
While these are household items that you could easily purchase at the store, please understand
that this is still for chemistry purposes. Do not INGEST anything or leave readily available for pets
and young children to get into (especially your chalk, um-l mean your final precipitate). All
items can be thrown away at the end. Ice melt solutions can be thrown away outside away
from pet areas. Even though Calcium Carbonate is relatively harmless-please note that this
should not be ingested.
Prelab:
1. If you had to make a 0.750M solution of Na₂CO3 from 100mL of solution, determine the
mass of Sodium Carbonate necessary.
1000 mL of 0.750m Solution contains 0.75 mol of Na₂CO3
100 mL of 0:750m Solution = 0.750x100 = 0.075 mol Na₂CO3
molar mass of Na₂CO3 = 105.988 g/m0000
0.075 mol NaCO3 =0.075x105.988 27.949 grams of Na₂CO3
2. If you had to make a 0.250M solution of CaCl₂ from 100mL of solution, determine the
mass of Calcium Chloride necessary.
1000 mL 0.250m Solution contains 0.25 mol CaCl2
100 m² of 0.250m solution = 0.25×100 =0.025 mol of CaCl₂
1000
mass of Sodium
Carbonate=
molar mass of CaCl₂=110.98g/mol
0.025 mol of CaCl2 = 0.025 x 110.98 = 2.77 grams of CaC1z
mass of Calcium
Chloride=;
7.949 grams
e=2.77 grams
3. If you use 10.0 mL of the Sodium Carbonate solution from #1 and an excess of Calcium
Chloride, how many grams of Calcium Carbonate should be theoretically be produced?
Na₂CO3(aq) +CaCl₂ (aq) →→CaCo3 + 2NaCl(aq)
10 mL of 0.75 m Na₂CO3 = 0.75×10=0.00 75 mol Na₂CO3
0.75 grams of
CaCo3 will be
theoretically
Produced
Imol Na₂CO3 reacts w/ Callz producing I mol caco 3
molar mass of CaCo3 = 100.086 g/mol
0.0075 mol of Calo 320.00 75% 100.086 = 0.75 grams of CaCo3
4. If you use 25.0 mL of the Calcium Chloride solution from #2 and an excess of Sodium
Carbonate, how many grams of Calcium Carbonate should be theoretically be
produced?
5. Using your answers from problems 3 and 4, what is the theoretical yield of 25.0mL of a
0.250M solution of CaCl2 when mixed with 10.0 mL of a 0.750M Sodium Carbonate
solution?
6. Suppose the student performs the experiment in the previous problem, what is the
percent yield if they generate 0.565g of CaCO3?
