Reef Chemistry Question of the Day #38
You folks are doing very well on these, so we'll start the week with a tough one.
Suppose you make concentrated seawater, either to try to raise salinity in a reef aquarium through a water change with high salinity seawater, or in the early stages of drying out seawater to collect salts from it.
What are the first three salts to precipitate from the drying or concentrated seawater?
A. Calcium carbonate, magnesium carbonate, magnesium sulfate
B. Calcium carbonate, magnesium sulfate, magnesium chloride
C. Calcium carbonate, calcium sulfate, magnesium sulfate
D. Calcium carbonate, calcium sulfate, magnesium carbonate
E. Calcium carbonate, magnesium carbonate, calcium chloride
Good luck!
