Question

How to make lead(II) nitrate from lead(II) sulfate?

Answer 1

You could add hot, concentrated nitric acid, `"HNO"_3`.

Explanation:

Balanced equation

`"PbSO"_4("s") + "2HNO"_3("aq")"` `rarr` `"Pb(NO"_3)_2("aq") + "H"_2"SO"_4("aq")"`

`"PbSO"_4` is insoluble in water and dilute acids. The `"HNO"_3` must be hot and concentrated.

Concentrated nitric acid is `70.4%` nitric acid (the rest is water), or `"15.9 M"`
