Ionic potential increases when…

Which cation is likely to attract water the least? (see the above table)

(Use the information in the previous question to answer this one) c) If [Cutotal] = {T} M and pH = {pH}, what is the concentration of free Cu2+ in the water sample?  Format answer in scientific notation and round to 3 significant figures.
