Chem help needed

[tanithryudo]

Cleaning out some crap from my closet and found some stuff that probably hails back from my high school days. There was a crystal growing kit (sans instructions) that I want to make sure I can get rid of without dumping hazardous materials where I shouldn't.

They're sealed bags of monoammonium phosphate, NH₄H₂PO₄.

So, can I dump this down the drain? Do I dump them in the trash?

According to the MSDS:

"12.Ecological Information
12.1 Ecotoxicity
Not determined.
12.2 Mobility
Not determined.
12.3 Persistence and degradability
Not relevant.
12.4 Bioaccumulative potential
Not determined
12.5 Other adverse effects
Ozone depletion potential: None
Photochemical ozone creation potential: None
Global warming potential: None

13.Disposal Considerations
No harm to the environment is expected from this preparation.
Dispose of in compliance with national, regional and local provisions that may be in force."

So, basically this means dump it in the trash if it's solid crystals and dump it in the drain if it's already a solute.

Huh... I did a google search for "monoammonium phosphate" and it tells me that it's used in fertilizer. Does that mean I can just bury them in the backyard or something? XD

Well, both ammonium and phosphate are extremely necessary compounds for plant growth and in large quantities in water would cause an algae bloom (and kill off all the fish in the process). But since your chemicals are in huge pure quantities, I wouldn't suggest using it for fertilizer. =.=

What if I dissolve it in water and then dump it in the yard? >.>

Well, if you know what the correct ratio is, go for it. It can't hurt. At least MSDS said so. XD
