🔬The experiment involves dissolving gold-plated pins to extract the gold content.
⚛️Nitric acid is used to dissolve the copper base metal, leaving behind gold foils.
🧪The process requires several gallons of nitric acid to fully dissolve the copper.
🔥Heat is applied to speed up the reaction and facilitate the dissolution process.
⏲️The experiment spans multiple days, with regular monitoring and addition of nitric acid.
What is the purpose of dissolving gold-plated pins?
—The purpose is to extract the pure gold content from the pins.
What is the role of nitric acid in the experiment?
