Question

What is the correct IUPAC name for AlPO₄?

pls show step by step

Answer 1

Here we have compound

AlPO₃

For any compound containing a metal ion we take it's full name first

Here aluminum

If the metal has multiple oxidation states and can form various compound with the same ions we include their oxidation state also

Then we name the second ion in front of the metal name

Here the ion name is phosphate

So

The name of the compound becomes

Aluminum phosphate
