Question

predict the chemical formula for the ionic compound formed by nh₄⁺ and po₄³⁻

Explanation:

Step1: Determine the charges

The ammonium ion \(\text{NH}_4^+\) has a charge of \(+1\), and the phosphate ion \(\text{PO}_4^{3 -}\) has a charge of \(-3\).

Step2: Balance the charges

To balance the charges, we need \(3\) \(\text{NH}_4^+\) ions to balance the \(-3\) charge of one \(\text{PO}_4^{3 -}\) ion.

Answer:

\((\text{NH}_4)_3\text{PO}_4\)
