CHEMISTRY SYNTHESIS OF CALCIUM CARBONATE INTRODUCTION
LABORATORY SIMULATION
1) In this experiment, you will be mixing aqueous solutions of sodium carbonate and calcium chloride to produce solid calcium carbonate.
Na2CO3(aq) + CaCl2(aq) → 2 NaCl(aq) + CaCO3(s)
Order the steps required to predict the volume (in mL) of 0.200 M calcium chloride needed to produce 2.00 g of calcium carbonate. There is al
Step 1
Convert the volume of calcium chloride solution required from liters to milliliters
Step 2
Convert mass of calcium carbonate to moles of calcium carbonate
Step 3
Compute the volume of calcium chloride solution required
Step 4
Compare moles of calcium carbonate to moles of calcium chloride based on balanced equation to calculate moles of calcium chloride required
2) Na2CO3(aq) + CaCl2(aq) 2 NaCl(aq) + CaCO3(8)
Calculate the volume (in mL) of 0.200 M CaCl2 needed to produce 2.00 g of CaCO3(3). There is an excess of Na2CO3.
Molar mass of calcium carbonate = 100.09 g/mol
Volume of calcium chloride =
100 ml
