2.43C Prepare a sample of pure, dry lead(II) sulfate question 1

[Maximum number: 3]

This question is about soluble salts and insoluble salts.

When solutions of lead nitrate and sodium sulfate are mixed, one product is solid lead sulfate.

This is the equation for the reaction.

Pb(NO3)2(aq)+Na2SO4(aq)→PbSO4( s)+2NaNO3(aq)\mathrm{Pb}\left(\mathrm{NO}_{3}\right)_{2}(\mathrm{aq})+\mathrm{Na}_{2} \mathrm{SO}_{4}(\mathrm{aq}) \rightarrow \mathrm{PbSO}_{4}(\mathrm{~s})+2 \mathrm{NaNO}_{3}(\mathrm{aq})

Describe how a pure, dry sample of solid lead sulfate can be obtained from the mixture.
