Unformatted text preview: alts has the highest concentration of silver ion when dissolved in water? AgCl Ksp = 1.6 x 10‐10 Ag2CO3 Ksp = 8.1 x 10‐12 AgBr Ksp = 5.0 x 10‐13 18. Which compound is least soluble in water? Ksp = 1.6 x 10‐15 a) Co(OH)2 b) Fe(OH)2 Ksp = 8.0 x 10‐16 c) AgBr Ksp = 5.0 x 10‐13 Ksp = 2.8 x 10‐9 d) CaCO3 Ksp = 8.7 x 10‐9 e) PbI2 Qualitative Analysis Group I (Section 17.7 & Lab Manual pages 35 – 48) 19. An aqueous solution contains the following twelve ions: Zn2+, Co2+, Pb2+, Ni2+, Cu2+, Sn2+, Fe2+, Sb3+, Al3+, Cr3+, Bi3+, and Ag+ and cold dilute HCl is added. What precipitate(s) will form? 20. Why must the dilute HCl added in to the solution in question 19 be cold? 21. Why is it better to use dilute HCl in question 19 dilute rather than use concentrated HCl? 22. In the group I analysis, what is the basis of separation for AgCl(s) and PbCl2(s). Why is this separation possible? 23. What color is PbCrO4(s)? Factors Influencing Solubility (Section 17.5) 24. How many moles of...
