Solution
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 \(\text{Cd}_3(\text{PO}_4)_2\).
