Answers to practice determining whether a precipitate forms:
1. no precipitate
2.
- precipitate,
- calcium sulfate, CaSO4,
- Ca2+(aq) + SO42¯(aq) → CaSO4(s)
3.
- precipitate,
- iron(III) hydroxide, Fe(OH)3,
- Fe3+(aq) + 3 OH¯(aq) → Fe(OH)3(s)
4.
- precipitate,
- copper(II) phosphate, Cu3(PO4)2,
- 3 Cu2+(aq) + 2 PO43¯(aq) → Cu3(PO4)2(s)
5. no precipitate
6.
- precipitate,
- barium sulfate, BaSO4,
- Ba2+(aq) + SO42¯(aq) → BaSO4(s)
7. no precipitate
8.
- precipitate,
- lead(II) carbonate, PbCO3,
- Pb2+(aq) + CO32¯(aq) → PbCO3(s)
9.
- precipitate,
- cobalt(II) phosphate, Co3(PO4)2,
- 3 Co2+(aq) + 2 PO43¯(aq) → Co3(PO4)2(s)
10.
- precipitate,
- copper(I) chloride, CuCl,
- Cu+(aq) + Cl¯(aq) → CuCl(s)
