Potassium hydroxide is an inorganic compound with the formula K OH, and is commonly called caustic potash. Along with sodium hydroxide (NaOH), KOH is a prototypical strong base. It has many industrial and niche applications, most of which utilize its caustic nature and its reactivity toward acids.
Although the pH of KOH or potassium hydroxide is extremely high (typical solutions typically range from 10 to 13), the exact value depends on the concentration of this strong base in water. Learn more about the Structure, physical and chemical properties of KOH from the experts at BYJU’S.
The molecular weight of KOH is approximately 56.11 g/mol. It has a melting point of about 360°C and a boiling point of 1,327°C. The chemical is extremely hygroscopic, readily absorbing water from the air and gradually transforming into a solution if left exposed.

17 Αυγ 2023 · Potassium hydroxide is a white solid with the formula K OH. It finds many applications in the lab as a general base, though sodium hydroxide is generally preferred as it is easier to find and slightly cheaper.
Formula and structure: The chemical formula of potassium hydroxide is KOH, and its molar mass is 56.11 g/mol. The structure of KOH consists of an ionic bond between the potassium metal cation and the hydroxyl anion, as shown below. Solid KOH is found in a rhombohedral crystalline structure, similar to that of sodium chloride.
1 Ιουλ 2024 · For example, when KOH reacts with hydrochloric acid (HCl), they form Potassium chloride (KCl) and water (H₂O). Equation : KOH + HCl → KCl + H₂O Hygroscopic
