Question
Which of the following acids dissolves gold in it?
Solution
El ácido que disuelve el oro es el agua regia. El agua regia es una mezcla de ácido nítrico (HNO₃) y ácido clorhídrico (HCl) en una proporción de 1:3. Esta combinación produce una solución altamente corrosiva que puede disolver el oro, algo que los ácidos individuales no pueden hacer por sí solos.
