An aqueous solution of an unknown salt of palladium is electrolysed to a current of 3.0 A passing for 1 hr . During electrolysis 2.977 g of palladium ions are reduced at the cathode . What is the charge on the palladium ions in solutions ?

Explanation

To determine the charge on the palladium ions in the solution, we can follow these steps:

### Step 1: Understand the Electrolysis Process
During electrolysis, palladium ions (Pd^n+) are reduced at the cathode to form solid palladium (Pd). The reduction reaction can be written as:
\[ \text{Pd}^{n+} + n \text{e}^- \rightarrow \text{Pd} \]
Here, \( n \) represents the number of electrons gained by the palladium ions.

### Step 2: Use Faraday's Laws of Electrolysis
