Please help, I have been trying to figure this out for some time:
For a lab I dissolved Calcium chloride with sodium carbonate each in water, then poured them into a funnel and filtered out a white pigment. I need to calculate the percent yield, but what is the white pigment. Is it calcium carbonate, sodium chloride, or something else?
