Product Overview

Potassium Hydroxide Pellets 85% Extra Pure (CAS No. 1310-58-3) is potassium hydroxide presented in pellet form at the stated assay. As a strong alkali, it provides hydroxide ions for acid neutralisation, hydrolysis, saponification and strongly basic reaction media. It also has a strong affinity for atmospheric moisture and reacts with carbon dioxide, factors that can progressively alter hydroxide content after prolonged exposure.

The Extra Pure grade is intended for routine preparative work and general laboratory solution preparation. Pellet form offers convenient portioning and handling relative to finely divided powder while retaining identical fundamental potassium hydroxide chemistry.

Typical Applications

• Preparation of potassium hydroxide solutions for routine laboratory use.
• Acid neutralisation and alkaline pH adjustment.
• Saponification of esters and fats in laboratory chemistry.
• Base-promoted hydrolysis and preparative transformations.
• General inorganic and organic synthesis requiring a strong potassium base.
• Alkaline reagent and reaction-medium preparation.

Common Synonyms

• Caustic potash
• Potash lye
• Potassium hydrate
• Potassium hydroxide
• Caustic potassium

Storage Conditions

Keep the container tightly closed and limit exposure of pellets to humid air to reduce deliquescence and surface moisture uptake. Minimise contact with atmospheric carbon dioxide because gradual carbonate formation can alter the effective hydroxide composition of material repeatedly exposed during use.
