Ammonium Phosphate Formula

Ammonium phosphate formula is a type of a more complex formula that students can come across while studying chemistry. Before learning the formula let us quickly understand what Ammonium phosphate is. It is a type of salt obtained during the reaction between concentrated phosphoric acid and ammonia. The salt is a colourless, odourless, crystalline solid which is not soluble in water. Additionally, it is a highly unstable compound and generally has a less commercial value. However, it is used as a food additive or as an emulsifier, flame retardant and in fertilizers.

Ammonium Phosphate Chemical Formula

The formula of ammonium phosphate is (NH4)3PO4. The salt compound consists of positively charged ammonium cations (NH4+) and phosphate anion (PO43-) which carries a -3 formal charge. Combining these two ions in the ratio of three to one or cross-multiplying the ionic charges gives us the formula.
