Kirkium is a made up metal element with a chemical symbol Km. The atomic mass of Km is 214.5 g/mol. The salt kirkium (III) hydroxide, Km(OH)3, is a slightly soluble salt that has a solubility product constant = 2.6×10-14.  You must show work in your upload for full credit. Enter your answers in E format, no spaces. Use correct sig figs! Do not enter units here but do show correct units in your upload.  A) Calculate the molar solubility of kirkium(III) ion in a saturated solution of Km(OH)3 dissolved in pure water. [s1] M B) Calculate the molar solubility of kirkium(III) ion in a saturated solution of Km(OH)3 dissolved in 0.040 M Ba(OH)2. [s2] M

If you want to correct ONE question, you can do so here.  Type in the question # (if you’re not sure of the number, take your best guess and describe what the problem was about so I can tell) Type in your corrected answer here. Be careful! Don’t second guess and convert a correct answer to an incorrect one. If it’s a calculation problem, show your new work in the file you upload. No work, no credit for the new answer. Do NOT erase the old work that supported your original answer. Show the new work separate from the old work, or cross out with a single line cross-out so that I can still see the original work. Sorry, only ONE question can be corrected. I’ll credit only the first one if you give me more than one corrected question. If you have no corrections, you may type “NA” in the space provided, so the exam recognizes that you answered the question.

Consider the formation reaction shown using the metal Snapeium (symbol Sp) and monodentate ligand L: Sp+(aq)  + [n] L (aq) SpL[n]+ (aq)  A solution initially has concentrations of Sp+ = 0.1[a]0 M and L = 0.0[b] M. When concentrations become constant the concentration of SpL[n]+ was found to be 0.0[c]0 M.       Calculate the formation constant, Kf. You must show work for full credit in your upload. Enter your answer in decimal form with correct sig figs. If you have difficulty in Canvas not accepting your answer, make sure it’s clearly shown in your work upload.
