Question

Which is the correct formula for copper(ii) phosphate?

a. cu(po3)2
b. cu2po4
c. cu2po3
d. none of those
e. cu(po4)2

Answer 1

The correct formula for copper(II) phosphate is e. Cu3(PO4)2, which occurs when three copper ions (2+ charge each) balance with two phosphate ions (3- charge each) to form a neutral compound. The option (A) is correct.

Step-by-step explanation:

The correct formula for copper(II) phosphate is Cu3(PO4)2. To determine the correct formula, we need to consider the charges of copper(II) and phosphate ions.

Copper(II) has a 2+ charge, while phosphate has a 3- charge. To balance the charges, we need two copper(II) ions and three phosphate ions, resulting in the formula Cu3(PO4)2. Therefore, option (A) is correct.
