Product Overview
Potassium hydroxide (KOH), offered at 99.98% purity on a trace metal basis, is a highly reactive alkaline compound supplied in pellet form for laboratory precision. This grade ensures minimal metallic contamination, making it ideal for applications requiring stringent purity standards. The pellets dissolve rapidly in water, generating significant heat and forming a strongly basic solution. Its hygroscopic nature demands careful handling and storage in airtight containers to prevent moisture absorption. The high assay guarantees consistent performance in titration, neutralization reactions, and as a catalyst in organic synthesis. Unlike lower-grade variants, this trace metal basis KOH minimizes interference in analytical procedures, ensuring reliable results. The pellet form provides convenient dosing while reducing dust hazards associated with powdered alternatives. Compatible with most glass and plastic labware, it remains stable under recommended storage conditions. For optimal shelf life, maintain in a cool, dry environment away from acids and carbon dioxide sources.
FAQs
1. What is the difference between trace metal basis and standard-grade potassium hydroxide?
Trace metal basis potassium hydroxide undergoes additional purification to reduce metallic impurities, ensuring higher accuracy in sensitive applications like titration or spectroscopy.
2. Can these pellets be used directly in aqueous solutions without further purification?
Yes, the 99.98% purity eliminates the need for additional purification in most laboratory procedures, though filtration may be required for particle-sensitive applications.
3. How does the pellet form compare to flakes or powder in terms of handling safety?
Pellets generate less airborne dust than powder, reducing inhalation risks, while offering more precise weighing than flakes during preparation.
4. What precautions should be taken when storing opened packages of these pellets?
Transfer to an airtight, moisture-resistant container with desiccant packs, as the pellets absorb atmospheric CO₂ and moisture, forming potassium carbonate over time.
5. Are there any compatibility issues with common labware materials when using this KOH?
Avoid prolonged contact with aluminum or zinc containers; use borosilicate glass or HDPE plastic for storage and handling to prevent corrosion.
