Product Overview
Lead monoxide LR (lead(II) oxide) is a high-purity laboratory reagent designed for demanding chemical applications where consistency and reactivity are critical. This yellow powder, also known as litharge, exhibits excellent thermal stability and solubility in dilute nitric acid, making it a versatile compound for synthesis and analytical procedures. The LR grade ensures minimal impurities, providing reliable results in qualitative analysis, precipitation reactions, and as a precursor in inorganic synthesis. Its fine particle size allows for uniform dispersion in solutions, while the controlled manufacturing process guarantees batch-to-batch reproducibility. The compound’s unique properties, including its basic nature and ability to form complex lead salts, make it particularly valuable in specialized laboratory protocols. Store in a tightly sealed container to prevent moisture absorption and maintain its reactive properties over extended periods.
FAQs
1. What is the difference between lead monoxide LR and AR grades?
LR grade contains slightly higher impurity levels compared to AR grade but remains suitable for most laboratory applications where ultra-high purity isn’t critical.
2. Can this lead monoxide be used for preparing lead-based pigments?
The LR grade purity makes it technically possible, though specialized pigment-grade oxides might offer better color consistency for artistic applications.
3. What safety precautions should be taken when handling this powder?
Use in a fume hood with proper PPE including gloves and goggles, as lead compounds pose both inhalation and contact hazards.
4. How does the reactivity compare to other lead oxides like Pb3O4?
Lead monoxide shows higher basicity and solubility in acids compared to red lead (Pb3O4), making it more suitable for certain synthesis routes.
5. What’s the typical shelf life when stored properly?
When kept in original packaging away from moisture, the product maintains its specifications for at least 24 months from manufacture date.
