1. A solution contains 1.43×10-2 M
sodium phosphate and
6.22×10-3 M potassium
hydroxide.
Solid aluminum nitrate is added slowly to this
mixture.
What is the concentration of hydroxide ion when
phosphate ion begins to precipitate?
[hydroxide] = M
2.A solution contains 9.99×10-3 M
calcium nitrate and
1.06×10-2 M barium
acetate.
Solid sodium fluoride is added slowly to this
mixture.
What is the concentration of calcium ion when
barium ion begins to precipitate?
[Ca2+] = M
3.A solution contains 1.19×10-2 M
potassium phosphate and
1.12×10-2 M ammonium
sulfide.
Solid zinc acetate is added slowly to this
mixture.
What is the concentration of sulfide ion when
phosphate ion begins to precipitate?
[sulfide] = M
