Write two points difference between .
Fused lead bromide and hot aqueous solution of lead bromide .

Explanation

### Step-by-Step Text Solution

**1. Conductivity:**
- **Fused Lead Bromide:** Fused lead bromide (PbBr2) is a good conductor of electricity. This is because, in its molten state, the lead and bromide ions are free to move without any hindrance, allowing for efficient conduction of electricity.
- **Hot Aqueous Solution of Lead Bromide:** In contrast, a hot aqueous solution of lead bromide conducts electricity, but not as effectively as the fused state. This is due to the hydration of ions by water molecules, which restricts their movement and decreases their ability to conduct electricity.

**2. Electrolysis Products:**
- **Fused Lead Bromide:** When electrolysis is performed on fused lead bromide, the products obtained are lead (Pb) at the cathode and bromine gas (Br2) at the anode.
