Calculate the minimum concentration of Cr^3+ that must be added to 0.095 mol/Litre NaF in order to initiate a precipitate of chromium(lll)flouride.
(For CrFsubnumber3,Ksubletterssp=6.6x10^-11)
10 precipitate - Will a precipitate of AgCl form whrn 0.050 mol NaCl(s) and 0.050 mol AgN0subnumber3(s) are dissolved in 500.0 milliliter of 3.0 mol/Litre NHsubnumber3 solution? ...
pH and precipitation - A 0.10 M Mn 2+ solution is saturated with H2S. At what pH will MnS begin to precipitate? [H2S] sat'd=0.10M
solid NaI slwly added to solution with Cu+ and Ag+. Calc. - Solid NaI is slowly added to a solution that is 0.013 M in Cu+ and 0.013 M in
Ag+.
Calculate [Ag+] when CuI just begins to precipitate.
What % of Ag+ remains in solution at this point?
