  • Answers to practice determining whether a precipitate forms:

    1. no precipitate

    2.

    1. precipitate,
    2. calcium sulfate, CaSO4,
    3. Ca2+(aq) + SO42¯(aq) → CaSO4(s)

    3.

    1. precipitate,
    2. iron(III) hydroxide, Fe(OH)3,
    3. Fe3+(aq) + 3 OH¯(aq) → Fe(OH)3(s)

    4.

    1. precipitate,
    2. copper(II) phosphate, Cu3(PO4)2,
    3. 3 Cu2+(aq) + 2 PO43¯(aq) → Cu3(PO4)2(s)

    5. no precipitate

    6.

    1. precipitate,
    2. barium sulfate, BaSO4,
    3. Ba2+(aq) + SO42¯(aq) → BaSO4(s)

    7. no precipitate

    8.

    1. precipitate,
    2. lead(II) carbonate, PbCO3,
    3. Pb2+(aq) + CO32¯(aq) → PbCO3(s)

    9.

    1. precipitate,
    2. cobalt(II) phosphate, Co3(PO4)2,
    3. 3 Co2+(aq) + 2 PO43¯(aq) → Co3(PO4)2(s)

    10.

    1. precipitate,
    2. copper(I) chloride, CuCl,
    3. Cu+(aq) + Cl¯(aq) → CuCl(s)
