news  Anyone know if diammonium phosphate is an acid or base? Sounds like a base to me..... It's amphoteric, actually- it swings both ways. Great. My wine additives are bisexual. Wonder what that does to the wine drinker...... Nothing more than the alcohol itself will do. I suspect it's more basic than acidic, but I'll have a chance to look up the numbers after class. I knew there was something I was forgetting to do. Diammonium phosphate contains the ammonium ion (NH4 +, a very weak acid) and the hydrogen phosphate ion (HPO4 2-), which is amphoteric. However, it's much more basic than acidic- if you had that ion in water without the ammonium, it would give a pH of about 10. The ammonium would moderate that a little- I calculate that a 0.1 mol/L sol'n of the salt would be about 8ish, which is basic. So, yeah, it's more basic than acidic.
