#Na_2SO_4(aq) + Pb(NO_3)_2(aq) rarr PbSO_4(s)darr + 2NaNO_3(aq)#


Get stoichiometric quantities of lead nitrate and sodium sulfate, and prepare separate solutions of each, maybe approx #0.1*mol*L^-1# with respect to the salt. Add the sodium sulfate to the lead solution dropwise with stirring. A fine white salt of lead sulfate will precipitate. This is to be collected on a frit, and then well-washed with distilled water (2-3 volumes), and then ethyl alcohol to aid in water removal. The fine solid will occlude a lot of water; dry under suction to a free flowing powder.
