Potassium Hydroxide Flakes ACS Grade

Product Overview

Potassium Hydroxide Flakes ACS Grade is a high-purity, white crystalline inorganic compound with the formula KOH. Commonly known as Caustic Potash or Potash Lye, this strong alkaline base is manufactured to meet the rigorous specifications of the American Chemical Society (ACS). It is a critical reagent for analytical laboratories, chemical synthesis, and industrial pH control where low impurity levels are essential.

This ACS-grade material is characterized by a typical assay of 98%, ensuring potent and predictable performance in base-mediated reactions and electrolyte formulations. Its low residue after ignition and strict limits on trace metals (such as iron and lead) prevent contamination in sensitive processing environments. The flake form allows for easy handling, weighing, and rapid dissolution in water, ethanol, and glycerol.

• Laboratory Reagent: Used in titrations, analytical methods, and the preparation of standard alkaline solutions for qualitative analysis.
• pH Control & Water Treatment: effective for neutralizing acidity and stabilizing pH levels in industrial effluent and processing water.
• Electrolyte Formulation: Serves as a primary component in alkaline battery electrolytes due to its high ionic conductivity.
• Industrial Processing: Utilized in biodiesel production, soap manufacturing (soft soaps), and specialized cleaning formulations.

Safety & Handling

Potassium Hydroxide is a Corrosive Solid (Class 8). It causes severe skin burns and eye damage. Proper Personal Protective Equipment (PPE), including chemical-resistant gloves, splash goggles, and face shields, must be worn during handling. Store in a cool, dry area in tightly closed containers, away from moisture, acids, and reactive metals (such as aluminum/zinc). This product is hygroscopic and will absorb moisture from the air rapidly.
