Why is nitrous acid oxidant as well as reductant ?

Text Solution

AI Generated Solution

To understand why nitrous acid (HNO2) acts as both an oxidant and a reductant, we need to analyze its oxidation state and the reactions it can undergo. Here’s a step-by-step breakdown of the explanation: ### Step 1: Identify the formula and oxidation state of nitrous acid - The formula of nitrous acid is HNO2. - To find the oxidation state of nitrogen in HNO2, we can set up the equation based on the known oxidation states of hydrogen and oxygen: - Let the oxidation state of nitrogen be \( x \). - The oxidation state of hydrogen (H) is +1, and for each oxygen (O), it is -2. ...
