CHAPTER 4: ANSWERS TO ASSIGNED PROBLEMS

4.69 (a) Which will have the highest concentration of potassium ion: 0.20 M KCl, 0.15 M K 2CrO 4, or 0.080 M K 3PO 4? Beware of dissociation! 0.20 M KCl 1 X 0.20 mol/L = 0.20 M K+ 0.15 M K 2CrO 4 2 X 0.15 mol/L = 0.30 M K+ 0.080 M K 3PO 4 3 X 0.080 mol/L = 0.24 M K+ 0.15 M K 2CrO 4 has the highest potassium ion concentration
