What Is Produced When Metal Oxides React With …

When metal oxides are put into contact with water, they often, though not always, form metal hydroxides. The reaction depends on the element, the acidity of the metal oxide and on the physical state of the water. It is generally the case that only weakly acidic or non-acidic metal oxides form metal hydroxides when in contact with water.
