ammonia and phosphoric acid combines to for mono-ammonium phosphate (MAP) and if MAP is further reacted with ammonia then it gives di-ammonium phosphate (DAP)
both reactions are exothermic in nature. reaction is as follows
NH3 + H3PO4 ------> (NH4)H2PO4 (MAP)
NH3 + NH4H2PO4 --------> (NH4)2HPO4 (DAP)
phosphoric acid
You can get DAP (Di-Ammonium Phosphate) or Map (Mono-Ammonium phosphate), depending on how they were reacted.
phosphine ignites in air at 150 degree to form phosphoric acid
H3PO4 is the formula for phosphoric acid, also called orthophosphoric acid. For details see: http://en.wikipedia.org/wiki/Phosphoric_acid
Phosphoric acid
Neutralize a few ml of phosphoric acid and add dilute nitric acid . Then add an equal volume of ammonium molybdate and warm. A bright canary-yellow precipitate is obtained which is soluble in dilute ammonia
I don't think so.poly phosphoric acid and phosphoric acid have same moleculer structure.http://harvestchem.iblogger.org
phosphoric acid
This reaction is:2 NH3 + H3PO4 = (NH4)2HPO4
You can get DAP (Di-Ammonium Phosphate) or Map (Mono-Ammonium phosphate), depending on how they were reacted.

Phosphoric acid
Phosphoric acid 85% is the highest purity of this type of acid available in the market. Which is most used in food grade. Phosphoric acid is in the classification of weak acids.
i think it is phosphoric is stronger but I'm not sure?
They are the same Chemical Formula. Basically the same Acid with two different names.
Bromic Acid Whoever wrote the above is a terrible idiot.... H3PO3 CANNOT be bromic acid as it contains no Bromine (Br on the periodic table) It's common name would be Phosphorous acid If it were H3PO4 it would be Phosphoric acid
