Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Understanding Hydrogen Peroxide (H₂O₂)**: - Hydrogen peroxide is a chemical compound with the formula H₂O₂. It is commonly used as a disinfectant and bleaching agent. 2. **Litmus Test**: - Litmus is a pH indicator that changes color in response to the acidity or basicity of a solution. Blue litmus paper turns red in acidic solutions and remains blue in neutral or basic solutions. ...

The strength of H_(2)O_(2) is expressed in several ways like molarity, normality,% (w/V), volume strength, etc. The strength of "10 V" means 1 volume of H_(2)O_(2) on decomposition gives 10 volumes of oxygen at 1 atm and 273 K or 1 litre of H_(2)O_(2) gives 10 litre of O_(2) at 1 atm and 273 K The decomposition of H_(2)O_(2) is shown as under : H_(2)O_(2)(aq) to H_(2)O(l)+(1)/(2)O_(2)(g) H_(2)O_(2) can acts as oxidising as well as reducing agent. As oxidizing agent H_(2)O_(2) is converted into H_(2)O and as reducing agent H_(2)O_(2) is converted into O_(2) . For both cases its n-factor is 2. :.
