Add the state symbols to the following formulae.
( ) indicates aqueous (dissolved in water)
( ) indicates solid (precipitate)
1. Lead Sulfate (PbSO₄)
Reactants: Lead(II) nitrate (Pb(NO₃)₂) and potassium sulfate (K₂SO₄)
Pb(NO₃)₂( ) + K₂SO₄ → PbSO₄( ) + 2KNO₃( )
Add the state symbols to the following formulae.
( ) indicates aqueous (dissolved in water)
( ) indicates solid (precipitate)
2. Barium Sulfate (BaSO₄)
Reactants: Barium nitrate (Ba(NO₃)₂) and potassium sulfate (K₂SO₄)
Ba(NO₃)₂(aq) + K₂SO₄(aq) → BaSO₄( ) + 2KNO₃( )

d) wash the salt with a minimum volume of distilled water
f) scrape the pure dry salt into the sample bottle.
e) dry the salt (leave in a warm dry place or press between dry filter paper)
b) filter the mixture
c) collect the residue (in the filter paper)
a) add the solutions of the two soluble salts together

Procedure for Preparing Insoluble Salts via Precipitation:

the soluble reactants: Dissolve each of the chosen soluble salts in separate beakers of distilled water.
: Carefully pour one solution into the other, stirring continuously. The insoluble salt will form as a precipitate.
Separate the precipitate by : Use filtration to separate the solid precipitate from the remaining solution (filtrate).
the precipitate: Wash the precipitate with distilled water to remove any remaining soluble ions.
the precipitate: Dry the precipitate by leaving it to air dry, or pressing between papers.
