A wаter sаmple is fоund tо cоntаin Cu but no organic or inorganic ligands except OH-. Assume that only one hydrolysis species contributes significantly to the total Cu in solution. (a) Using the soluble species in the chemical reaction below, write a mass balance expression for the concentration of total soluble Cu. (Place Cutotal on the left side of the equation.) 5 points K log Kf Cu2++H2O⇌Cu(OH)++H+{"version":"1.1","math":"Cu2++H2O⇌Cu(OH)++H+"} 10-7.52 -7.52 (b) Express Cutotal in terms of free (Cu2+) (that is, (Cu2+) should occur in all terms on the right side of the equation). 10 points Show your work to the best of your ability here, and upload an image of your scratch paper. If you cannot type out your work, be sure that it is included on the scratch paper. You can upload your scratch paper by clicking on the camera icon or by clicking Add a File. You may alternatively do the same in the show work question below. If this doesn't work, add the image to the Exam 1 - Scratch Paper Dropbox located in the Assignments tab of this D2L site after you submit this exam.
