pure chemistry ⚗️, Pure gold does not react with nitric acid because gold is a noble metal, but nitric acid does dissolve base metals (like copper, silver) in gold alloys, allowing for purification; to dissolve gold itself, you need aqua regia, a mix of nitric and hydrochloric acid, which creates a strong oxidizing and complexing environment for gold to dissolve into chlorauric acid.
