When lead nitrate and magnesium sulfate react a precipitate is formed identify the white precipitate and give a reason and write ionic equation for the reaction ?

The white precipitate formed when lead nitrate and magnesium sulfate react is lead sulfate (PbSO4). This precipitate forms because lead ions (Pb2+) from lead nitrate react with sulfate ions (SO4 2-) from magnesium sulfate to form an insoluble lead sulfate compound.

The ionic equation for the reaction is:

Pb(NO3)2 (aq) + MgSO4 (aq) -> PbSO4 (s) + Mg(NO3)2 (aq)

White precipitate: Lead sulfate (PbSO₄)

Reason: Lead sulfate is insoluble in water and forms a white precipitate when lead nitrate (Pb(NO₃)₂) and magnesium sulfate (MgSO₄) react.

Ionic equation for the reaction:

```
Pb²⁺(aq) + SO₄²⁻(aq) → PbSO₄(s)
```

Explanation:

When lead nitrate and magnesium sulfate are dissolved in water, they dissociate into their respective ions:

```
Pb(NO₃)₂(aq) → Pb²⁺(aq) + 2NO₃⁻(aq)
MgSO₄(aq) → Mg²⁺(aq) + SO₄²⁻(aq)
```

Lead ions (Pb²⁺) and sulfate ions (SO₄²⁻) then combine to form lead sulfate, which is insoluble in water and precipitates out of solution as a white solid. The remaining magnesium ions (Mg²⁺) and nitrate ions (NO₃⁻) remain in solution.
