Answer :
To determine the correct chemical formula for ammonium phosphate, follow these steps:
1. Identify the ions involved:
- Ammonium ion: [tex]\( NH_4^+ \)[/tex]
- Phosphate ion: [tex]\( PO_4^{3-} \)[/tex]
2. Balance the charges:
- The phosphate ion has a charge of [tex]\( 3- \)[/tex].
- The ammonium ion has a charge of [tex]\( 1+ \)[/tex].
3. Determine the number of ammonium ions needed to balance the charge of one phosphate ion:
- If each ammonium ion has a charge of [tex]\( 1+ \)[/tex], you will need three ammonium ions to balance the [tex]\( 3- \)[/tex] charge of one phosphate ion: [tex]\( 3 \times (NH_4^+) = 3+ \)[/tex]
4. Write the chemical formula:
- Combine the ions with the determined ratio from the previous step:
- The correct formula is [tex]\( (NH_4)_3PO_4 \)[/tex].
Thus, the correct chemical formula for ammonium phosphate is:
C. [tex]\( (NH_4)_3PO_4 \)[/tex]
