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.
Acid–base reactions require both an acid and a base. In Brønsted–Lowry terms, an acid is a substance that can donate a proton (H +), and a base is a substance that can accept a proton. All acid–base reactions contain two acid–base pairs: the reactants and the products.
1 Ιουλ 2024 · What is Potassium Hydroxide? Potassium hydroxide is often abbreviated as KOH and it is a powerful chemical base widely used in various industries and applications. It appears as a white, solid substance that dissolves readily in water, producing heat and forming a solution known as lye.
We will use this standard solution to obtain the concentration of a BASE (either KOH or NaOH) solution. We will use the base solution to titrate the vinegar solution. Since we are using a known concentration of base, the technique is also referred to as alkalimetry.
It is very soluble in water, forming a strongly alkaline solution. It is also soluble in ethanol and glycerol, though not as soluble in ether and other non-polar solvents. The molecular weight of KOH is approximately 56.11 g/mol.
POTASSIUM HYDROXIDE, SOLUTION is a strong base dissolved in water. Reacts exothermically with all acids. Slowly dissolves glass. Attacks aluminum and zinc to generate flammable hydrogen gas. Ignited a polyethylene container liner when mixed with potassium persulfate by release of heat and oxygen [MCA Case History 1155. 1955].
