Product Overview
Potassium hydroxide (KOH) flakes at 85% purity offer a concentrated alkaline solution for demanding laboratory applications. These white, odorless flakes are highly hygroscopic, absorbing moisture rapidly from the air, which necessitates careful handling and storage in airtight containers. The technical-grade formulation ensures consistent performance in chemical reactions where precise pH control is critical. As a strong base, KOH flakes dissolve exothermically in water, generating significant heat, which requires gradual addition to prevent splattering. The material’s corrosive nature demands compatibility with glass or high-density polyethylene containers, while its solubility in water (110g/100mL at 20°C) makes it versatile for preparing aqueous solutions. The flake form provides easier handling compared to pellets, allowing for accurate weighing without dust generation. This product maintains stability under normal conditions but reacts violently with acids and organic materials, requiring proper ventilation during use.
FAQs
1. What is the shelf life of 85% potassium hydroxide flakes when stored properly?
When kept in a tightly sealed container away from moisture and carbon dioxide, the flakes retain their potency for up to 2 years.
2. Can these KOH flakes be used directly without dissolving?
The flakes can be used directly in solid form for certain reactions, but most applications require dissolution in water or alcohol.
3. What safety precautions are essential when handling these flakes?
Always wear chemical-resistant gloves, goggles, and a lab coat, and work in a fume hood due to the corrosive nature and potential for exothermic reactions.
4. How does the flake form compare to pellet form for laboratory use?
Flakes dissolve faster than pellets and are easier to weigh accurately, though they may require more careful handling to avoid moisture absorption.
5. What materials are incompatible with potassium hydroxide flakes?
Avoid contact with aluminum, zinc, tin, and some plastics, as KOH reacts violently with these materials, causing degradation or hazardous gas release.
