How many moles of `H_2O_2` will be requried to react completely with 1.5 " mol of "`K[Cr(OH)_4]` (potassium tetrahydroxochromate (I)) in basic medium?

Explanation

To determine how many moles of \( H_2O_2 \) are required to react completely with 1.5 moles of \( K[Cr(OH)_4] \) in a basic medium, we can follow these steps:

### Step 1: Identify the Reaction
In a basic medium, hydrogen peroxide (\( H_2O_2 \)) acts as a reducing agent. The potassium tetrahydroxochromate (I) will be oxidized to chromate ion (\( CrO_4^{2-} \)).

### Step 2: Determine the Oxidation States
1. The oxidation state of chromium in \( K[Cr(OH)_4] \):
- Let the oxidation state of Cr be \( x \).
