Question: What Does Nitric Acid Do To Skin?

What is the significance of adding nitric acid solution?

Adding HNO3 converts metal ions into their nitrate salts, which are highly soluble.

Secondly, sample digestion is required before AAS.

The purpose is to destroy the matrix, which otherwise interfere during atomization.

Also digestion converts all form of metal into a single oxidation state..
