Write IUPAC name of `K_2[PdCl_4]`

Explanation

To determine the IUPAC name of the compound \( K_2[PdCl_4] \), we can follow these steps:

### Step 1: Identify the components of the compound
The compound consists of potassium ions and a coordination complex. The coordination complex is \( [PdCl_4]^{2-} \).

### Step 2: Determine the oxidation state of the central metal
Let the oxidation state of palladium (Pd) be \( x \). The chloride ions (Cl) have a charge of -1 each. Since there are 4 chloride ions, the total charge contributed by the chloride ions is \( -4 \). The overall charge of the coordination complex is -2 (as indicated by the 2 potassium ions balancing it).
