Hey guys i need a solution to this problem, any one can give me the most understanding one will recieve points

Consider 100. mL samples of 0.10 M aqueous solutions of cobalt (II) acetate, cobalt (II) chloride, cobalt (II) nitrate, and cobalt (II) sulfate. The pK value for cobalt (II) ion is 8.89 at 25 degree C. Kw. = 1.0 Times 10-14. Do you expect the pH of each of these solutions at 25 degree C to be less than 7, equal to 7, greater than 7, or cannot be determined? Justify your choice. Order these solutions from lowest to highest pH, clearly indicating which solution has the lowest pH. Justify your choice.
