How would each of the following modifications to the experimental procedure used in this investigation affect the mass of the product obtained? Indicate if the mass of the product would be greater, less, or unchanged. Explain your reasoning.
(Note: CaCO3 is slightly soluble in water)
The CaCl2 solution is added to the Na2CO3 solution instead of adding the Na2CO3 solution to the CaCl2 solution.
b. The temperature of the reactant solutions is 40°C instead of room temperature.
c. The residue is washed with hot distilled water instead of cold distilled water.
d. The residue is not washed with distilled water at all.
e. The reactions were performed using 20.00 mL of 1.00 M Na2CO3 instead of 20.00 mL of 0.500 M Na2CO3.
