What is shelf life for Nitric Acid?

The shelf life of nitric acid depends on its concentration and storage conditions. Generally, concentrated nitric acid can last for several years if stored properly in a cool, dry place away from light and incompatible materials. However, over time, it may decompose and release nitrogen dioxide, which can affect its effectiveness. For best results, it's advisable to check for any changes in appearance or odor and refer to manufacturer guidelines.
