The video explores whether magnesium oxide (MgO) is soluble in water. It begins by introducing the question and then reviews solubility rules, noting that oxides are generally insoluble except for sodium and potassium. A solubility chart is used to confirm that MgO is insoluble, although a very small amount may dissolve. The video concludes by reiterating that MgO is insoluble in water.
