What is the net ionic equation for the reaction of

lead(II) nitrate with potassium iodide?

• 2 PbNO₃(aq) + KI(aq) → 2 PbI(s) + KNO₃(aq)

• Pb₂NO₃(aq) + KI(aq) → Pb₂I(s) + KNO₃(aq)

• Pb²⁺(aq) + 2 NO₃^-(aq) + 2 K⁺(aq) + 2 I^-(aq) → PbI₂(s) +

  2 KNO₃(aq)

• Pb²⁺(aq) + 2 I^-(aq) → PbI₂(s)

• K⁺(aq) + NO₃^-(aq) → KNO₃(s)

If you sprinkled table salt into a saturated solution

of lead(II) chloride, what would happen to the

concentrations of the dissolved lead and chloride

ions?

• The lead ion concentration would decrease and

  the chloride concentration would increase.

• The chloride concentration would increase but

  the lead ion concentration would stay the same.

• The table salt would not dissolve, so the lead and chloride concentrations would remain unchanged.

• The lead ions would precipitate out the added chloride ions, so both the lead and chloride ion concentrations would decrease from their initial levels.

• The chloride concentration would increase until

  it was equal to the lead concentration, then no

  more table salt would dissolve.
