Product Overview
Nitric acid 69% extra pure is a highly concentrated, colorless to pale yellow liquid with strong oxidizing properties, making it indispensable in laboratory settings. This reagent-grade acid is meticulously purified to minimize impurities, ensuring consistent performance in critical applications such as metal dissolution, nitration reactions, and sample digestion for analytical testing. Its high reactivity demands careful handling, with storage in corrosion-resistant containers and usage in well-ventilated areas. The extra pure grade guarantees minimal interference in sensitive procedures, providing reliable results for researchers and technicians. Compatible with most glassware, it is widely used in inorganic synthesis, electroplating, and as a cleaning agent for laboratory equipment. Always follow standard safety protocols, including the use of protective gear and proper neutralization before disposal, to mitigate risks associated with its corrosive nature.
FAQs
1. What is the shelf life of 69% nitric acid?
When stored in a tightly sealed, airtight container away from heat and light, nitric acid 69% retains its potency for up to 2 years. Over time, slight yellowing may occur due to nitrogen dioxide formation.
2. Can this nitric acid be used for gold testing?
Yes, 69% nitric acid is commonly used in aqua regia preparations for gold dissolution and purity testing. However, it should be diluted and handled with extreme caution.
3. Is this acid compatible with plastic containers?
No, nitric acid reacts with most plastics and organic materials. Always store it in glass or PTFE-lined containers to prevent leaks or contamination.
4. What safety precautions are essential when handling this acid?
Wear nitrile gloves, safety goggles, and a lab coat. Work under a fume hood, and have a neutralizing agent like sodium bicarbonate ready in case of spills.
5. How does this compare to 70% nitric acid?
The 69% concentration is nearly identical in reactivity to 70%, with negligible differences in performance for most lab applications. The extra pure grade ensures fewer impurities.
