I just want to make sure I have this right. I know the general solubility rules (i.e. nitrates are highly soluble, hydroxides aren't, etc.), but I'm not completely sure how to compare the solubilities of two salts of the same anion. I'm pretty sure that the salt with the more reactive ion attached to it will be more soluble, since higher reactivity means lower energy required to break the ionic bond between the two ions. For example, if the two salts are KOH and Ca(OH)2, KOH should be more soluble because K is more reactive than Ca. Would this be a fair generalization of the degree of solubility?
