What precipitate forms when you mix barium nitrate with sodium nitrate?

• sodium nitrate 
• barium nitrate since the reaction is reversible

• there will be no reaction and thus no precipitate

• sodium sulfate

What precipitate forms when you mix lead (II) nitrate with sodium chloride?

• sodium nitrate 
• lead (II) chloride 
• sodium lead
• chloride nitrate 

Which of these results in the formation of a precipitate?

• AgNO₃(aq) + NaOH(aq)→

• Ba(NO₃)₂(aq) + CaCl₂(aq)→

• NaNO₃(aq) + KOH(aq)→

• More than one of these form precipitates
