the formaula for the compound formed between aluminum ions and phosphate ions is???
a. Al3(PO4)3
b. AlPO4
c. Al(PO4)3
d. Al2(PO4)3
e. AlP
To determine the formula for the compound formed between aluminum ions (Al3+) and phosphate ions (PO43-), we need to balance the charges of the ions.
First, let's determine the charge on the aluminum ion. Aluminum (Al) typically loses three electrons to form a 3+ cation, Al3+.
Phosphate (PO43-) is made up of one phosphorus atom (P) and four oxygen atoms (O). The charge on the phosphate ion is 3-.
Now, we need to balance the charges. Since the aluminum ion has a 3+ charge and the phosphate ion has a 3- charge, we need three phosphate ions to combine with two aluminum ions in order to balance the charges.
The correct formula for the compound formed between aluminum ions and phosphate ions is (d) Al2(PO4)3.
So, the answer is d. Al2(PO4)3.
The formula for the compound formed between aluminum ions (Al3+) and phosphate ions (PO4-3) is AlPO4.
Therefore, the correct answer is b. AlPO4.
