Ionic and Covalent Bonds in KOH

The video explores whether potassium hydroxide (KOH) is ionic or covalent. KOH is an ionic compound due to the bond between potassium (a metal) and hydroxide (a non-metal). However, within the hydroxide ion, there is a covalent bond between oxygen and hydrogen. The video explains the ionic charges of potassium and hydroxide, highlighting the attraction between positive and negative ions. It concludes that while KOH is overall ionic, it contains a covalent bond within the hydroxide ion.
