Ammonium phosphate is described as not alkaline in its reaction. Which option matches this description?

Explanation:
The key idea is how ammonium salts behave in water. Ammonium phosphate contains the ammonium ion, which acts as a weak acid in solution. When it dissolves, NH4+ can donate a proton, forming H3O+ and lowering the pH. The phosphate part can buffer but does not produce a strongly basic solution. Because of this acid‑forming tendency, the reaction is not alkaline. That’s why the description that fits best is “Not alkaline in its reaction.”
