Hi! So I m working in a lab project, i which I did the following step. Sodium hydrogen phosphate (Na₂HPO₄) is acidified with nitric aid (HNO₃) and later reacts with zirconyl chloride (ZOCl₂).

I wrote the following reaction:

2H₃PO₄ + ZrOCl₂ -> Zr(HPO₄)₂ +2HCl + H₂O

Yet, my teacher said its wrong because phosphoric acid (H₃PO₄) is not used.

So my question is: What is the correct equation for this project?
I need ONE main equation that covers all aspects. Does anyone know how to do this?
I am really confused and I appreciate all your help

You have to implement NaH₂PO₄ + HNO₃ => H₃PO₄ + NaNO₃.

Try to substitute this in your equation by yourself.
