Describe the oxidizing action of with the following. `K_(2) Cr_(2) O_(7)`Write ionic equations for its reaction (acidic medium) with :
Iron (II)

Explanation

To describe the oxidizing action of potassium dichromate (\(K_2Cr_2O_7\)) and write the ionic equation for its reaction with iron(II) ions (\(Fe^{2+}\)) in acidic medium, we will follow these steps:

### Step 1: Identify the Oxidizing Agent
Potassium dichromate (\(K_2Cr_2O_7\)) is a strong oxidizing agent, especially in acidic medium. In acidic conditions, the dichromate ion (\(Cr_2O_7^{2-}\)) can accept electrons and undergo reduction.

### Step 2: Write the Reduction Half-Reaction
In acidic medium, the reduction of dichromate ion can be represented as follows:
\[
