Reef Chemistry Question of the Day [HASHTAG]#141[/HASHTAG]
Consider a common magnesium supplement made from 10 parts of magnesium chloride and 1 part of magnesium sulfate. Both salts are highly soluble in fresh water so one can easily make a very concentrated solution for dosing.
Now that you have your stock solution, you are wondering what else you might be able to mix into it to dose at the same time.
You do some experimenting and find that something you wanted to add in a very concentrated solution didn't work out, resulting in precipitation of solids.
Which of the following could NOT have been what you added, because it wouldn't result in a precipitate? (ignore for the moment whether you personally want to dose this or not; people have dosed all of these)
You may elect more than one, if you think it appropriate
A. Calcium chloride
B. Muriatic acid (hydrochloric acid)
C. Sodium hydroxide
D. Acetic Acid (primary ingredient of vinegar)
E. Sodium carbonate
F. Ethanol (primary ingredient of Vodka)
For the most credit, explain your rationale for the answers
Good luck!
