Please help asap =) 2. Lead(II)chloride is insoluble in water Kap PbCn 1.7x10-) and silver chloride is very insoluble in water (Ksp Agci 1.8x10-10). The reactions when they go into solution are: AgCl(s) ←→ Ag+(aq) + Cl-(aq) PbCl2(s)艹Pb+2(aq) + 2 Cl-(aq) a. What are the expressions for the equilibrium constants, Kop for the above reactions? b. Explain why it is possible to dissolve more lead(I)chloride in solutions in which the concentration of the silver ion is present. c. Explain what...

The copper(Il) ion reacts with phosphate ion to form an insoluble ionic compound, Ksp- 1.40x10-37.The copper(Il) ion also forms a complex ion with ammonia, [Cu(N Halal2+, Kf-5.03x 1013. Write the chemical reaction that occurs between aqueous ammonia and solid copper(II) phosphate.
Which of the following ions will form a precipitate with the lead (II) cation in solution? Name all that apply Ag+, Cl-, F-, NO3-, SO42-
Soluble Ions 1. Cations 2. Anions Empirical Solubility Rules The presence of these ions tend to make the ionic compound water soluble (note exceptions). Ions Exceptions (compounds are insoluble despite having these cations) Li", Na, K, Exceptions = Li,Co, and LigPO4 NH Exceptions (compounds are insoluble Ious despite having these anions) NO,, nitrate ion No exceptions, all nitrates are water soluble C₂H₂O₂: No exceptions, all acetates are water soluble No acetate ion CIO4, CIO3. No exceptions, all perchlorate and chlorate...
Once contaminated, polluted water sources must be treated or they represent a hazard to local residents. We have mentioned before that lead (Pb2+) ions are a particularly dangerous pollutant. How do we remove ions that we can't even see? Here our understanding of solubility can help. If we add an anion that forms an insoluble salt with Pb2+ ions, we could filter off the solid that forms and remove much of the lead contamination. Use what you know to help....
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...
