Classify whether KOH is a strong or weak acid, a strong or weak base, or a salt.
KOH is potassium hydroxide. Since it is composed of the hydroxide anion (OH-), it is a strong base. In solution, the hydroxide anion will completely react with any available protons, that is why KOH is a strong base. It is not an acid of any type, weak or strong, since KOH does not contribute any protons to solution. KOH is a salt since it is composed of inorganic ions and forms a solid in the absence of any solvent. The two ions (K+ and OH-) completely ionize in water. So KOH is both a strong base and a salt.
