So it's a white ionic compound. Well, that narrows it down to just about every ionic compound that doesn't contain copper or iron! :P But you've also said it's basic, which means it must be created with a strong base and a weak acid. That means its cation is either Na or K, but since you've said it isn't Na, then it must be a potassium compound, or potentially a lithium compound, but that's less likely. Now that just leaves the anion. Damn, while there's only a very limited list of strong acids and bases, there are tonnes of weak ones. So, common everyday ionic substances with potassium as the cation. Hmm, let me get back to you on that one. So, is the cation of this ionic substance potassium?
