C
Ammonium phosphate
D
Ammonium phosphide
Verified step by step guidance1
Identify the ions present in the compound (NH4)3PO4. The compound consists of ammonium ions (NH4^+) and phosphate ions (PO4^{3-}).
Recall the charges of the ions: ammonium ion (NH4^+) has a charge of +1, and phosphate ion (PO4^{3-}) has a charge of -3.
Check the formula to confirm the ratio of ions: three ammonium ions (each +1) balance one phosphate ion (-3), making the compound electrically neutral.
Use the IUPAC naming convention for ionic compounds: name the cation first (ammonium) followed by the anion (phosphate).
Verify the options given and select the name that correctly reflects the ions and their charges: 'Ammonium phosphate' is the correct IUPAC name for (NH4)3PO4.
