A solution of NaOH is added dropwise to a solution that is 0.0224 M in Fe2+ and 3.60e-15 M in Ga3+. The Ksp of Fe(OH)2 is 4.87e-17. The Ksp of Ga(OH)3 is 7.28e-36. (a) What concentration of OH- is necessary to begin precipitation? (Neglect volume changes.) [OH-] = M (b) Which cation precipitates first? Fe2+ Ga3+ (c) What is the concentration of OH- when the second cation begins to precipitate? [OH-] = M

Determine whether a precipitate form in the following reaction conditions: a. A solution containing lead (II) nitrate is mixed with one containing sodium bromide to form a solution that is 0.0150 M in Pb(NO3)2 and 0.00350 M in NaBr. Does a precipitate form in the newly mixed solution? Ksp PbBr2 = 4.67 x 10-6 . b. A solution containing iron (II) nitrate is mixed with one containing sodium phosphate to form a solution that is 0.0365 M in Fe(NO3)2 and...

I have 1.01 of a solution that is 0.100M Fe(NO3)2 and 0.200M Cu(NO3)2. I want to seperate the metal ions. I gradually add a solution that is 0.100M in K3PO4, 0.100 M in KOH, and 0.100 M in K2CO3.What volume of the solution do I need to add to get the first metal to begin to precipitate?

Let us assume that Cd(OH)2(s) is completely insoluble, which signifies that the precipitation reaction with NaOH(aq) (presented in the transition) would go to completion. Cd2+(aq)+2NaOH(aq) → Cd(OH)2(s)+2Na+(aq) If you had a 0.450 L solution containing 0.0190 M of Cd2+(aq), and you wished to add enough 1.31 M NaOH(aq) to precipitate all of the metal, what is the minimum amount of the NaOH(aq) solution you would need to add? Assume that the NaOH(aq) solution is the only source of OH−(aq) for the...
