Web4 apr. 2024 · K2O is an ionic compound because when the metal combines with nonmetal, it usually forms an ionic compound. Here, K is a metal and O is a nonmetal. So when they combine, it forms an ionic compound. Well, now you have got to know that K2O is an ionic compound, but let me explain the in-depth reason why K2O is an ionic compound. WebThe oxide ion reacts with water molecules to form hydroxide ions as k2o dissolves in water. Is there a basic solution in water produced by K2O? Metal oxides that dissolve in water form bases, and K2O would be a strong base. CuO, for example, is insoluble in water.
