What Is Produced When Metal Oxides React With Water ...

It is generally the case that only weakly acidic or non-acidic metal oxides form metal hydroxides when in contact with water. The oxides that react in this way with water are called basic oxides. In addition, most metal hydroxides are formed only with cold water. Metal hydroxides break down into their constituent parts when exposed to high heat.
