I mean, will some metal oxide ,which is completely insouble in the water , such as MgO , form a slightly alkaline solution after you put it in a glass of water?

It is because when the metal oxide reacts with water,hydroxide ions (OH-) has formed,so it will form a slightly alkaline solution,although that chemical is slightly soluable,like Calcium Hydroxide {Ca(OH)2}
