How would the following modifications of the experimental procedure used in this experiment affect the mass of the precipitate collected? Indicate whether the mass would be greater than, unchanges, or less than that obtained. Briefly explain the answer.

a, Adding the CoCl2 solution to the Na3PO4 solution, instead of the reverse

b. Performing the reaction at 40 degrees Celsius, instead of at room temperature

c. The residue collected on the filer paper was not washed with cold water?

d. The residue was washed with hot distilled, deionized water instead of cold distilled, deionized water

e. 6.00mL of 2.00M CoCl2 reacted with 1.00mL 1.00M Na3PO4 instead of reacting 6.00ML of 1.00M CoCl2 with 1.00ML 1.00M Na3PO4
