Reef Chemistry Question of the Day [HASHTAG]#126[/HASHTAG]
Two of the primary materials used as inorganic binders of phosphate are GFO (granular ferric oxide) and aluminum oxide. GFO is always a dark color, varying from orange to red to nearly black, depending on hydration and possibly other factors. Aluminum oxide binders are always white.
What is the chemical formula for the aluminum oxide used as a phosphate binder?
A. AlO
B. AlO2
C. Al2O
D. Al2O2
E. Al2O3
F. Al3O2
G. Al3O3
Bonus: why is that the formula?
Good luck!
