Reef Chemistry Question of the Day #191
This is a follow up question to question 189: Evaporation of Organic Dosing Compounds
Aquarists use a variety of organic compounds for dosing to drive bacterial growth and reduce nutrients. Sometimes these solutions may sit around a long time before or during dosing.
When a solution of the following chemicals is mixed at equal concentrations and then allowed to sit for a very long time at room temperature, which chemical will have the highest concentration at the top of the fluid in the dosing reservoir?
A. Methanol (one component of NOPOX)
B. Ethanol (as in vodka and NOPOX)
C. Acetic Acid (as in vinegar and NOPOX)
D. Isopropanol (one component of NOPOX)
E. Water
F. All will be at the same concentration
Good luck!
