Solution Steps

Step 1: Identify the Chemical Formula for Cadmium Phosphate

Cadmium phosphate is a compound formed by cadmium (Cd) and the phosphate ion (\(\text{PO}_4^{3-}\)). To determine the correct formula, we need to balance the charges between cadmium and phosphate.

Step 2: Determine the Charges of Cadmium and Phosphate
  • Cadmium (Cd) typically has a charge of \(+2\).
  • The phosphate ion (\(\text{PO}_4\)) has a charge of \(-3\).
Step 3: Balance the Charges

To balance the charges, we need to find the smallest whole number ratio of cadmium ions to phosphate ions that results in a neutral compound.

  • Let \(x\) be the number of cadmium ions and \(y\) be the number of phosphate ions.
  • The equation to balance the charges is: \(2x = 3y\).

Solving for the smallest whole numbers, we get:

  • \(x = 3\) (cadmium ions)
  • \(y = 2\) (phosphate ions)
Step 4: Write the Chemical Formula

The chemical formula for cadmium phosphate, based on the balanced charges, is \(\text{Cd}_3(\text{PO}_4)_2\).

Final Answer

\[ \boxed{\mathrm{Cd}_{3}\left(\mathrm{PO}_{4}\right)_{2}} \]
