Write net charging and discharging reactions for lead storage battery.

Explanation

### Step-by-Step Solution

**1. Understanding the Lead Storage Battery:**
- A lead storage battery, also known as a lead-acid battery, consists of lead (Pb), lead dioxide (PbO2), and sulfuric acid (H2SO4). It operates through redox reactions during charging and discharging.

**2. Charging Reaction:**
- During charging, electrical energy is supplied to the battery, reversing the discharging process.
- **Anode Reaction:**
