FAQ

Those who are looking for an answer to the question «Will hydrochloric acid and hydrogen peroxide dissolve gold?» often ask the following questions:

👉 Does hydrogen peroxide dissolve gold?

Instead of nitrate as an oxidizer, you're using hydrogen peroxide, which is also a powerful oxidizer. The hydrogen peroxide oxidizes the gold and the chloride ions form soluble complexes. Also happening is the dissolution of oxygen into the acid, which helps dissolve gold.

👉 Quick answer: does hydrogen peroxide dissolve gold?

The hydrogen peroxide oxidizes the gold and the chloride ions form soluble complexes. Also happening is the dissolution of oxygen into the acid, which helps dissolve gold… It will react with oxides of copper forming water with the oxygen and hydrogen ion leaving a copper ion to form a compound with the chloride ion.

👉 Does hydrogen peroxide dissolve silver?

Ordinary silver dissolves with difficulty in a 1:1 mixture of 5% acetic acid and 3% hydrogen peroxide… However, "anodizing" the silver in a salt water bath corrodes the surface, allowing it to dissolve in the aqueous solution.

In it, he starts off with 2 parts muriatic and 1 part 3% hydrogen peroxide (H2O2 - a source of needed oxygen). Your 32% HCl is close to the same HCl strength as muriatic. For a long time, most people used this formula and many still do. Notice that Steve says it will dissolve gold also if you heated it.

How do you dissolve gold at home? Pour 30 milliliters of nitric acid for every ounce of gold into your container. Allow the acid to react with the gold for 30 minutes. Add 120 milliliters of hydrochloric acid or muriatic acid for every ounce of gold in the container.

Mixing muriatic acid (hydrochloric acid) with bleach (sodium hypochlorite), you are freeing chlorine to attack the gold. You are making gold chloride. Try exposing the solution to ultraviolet light, to break the bond between the gold and the chlorine molecules.

1. Hydrofluoric acid does not decompose hydrogen peroxide but acts as a stabilizer. The other halogen hydrides cause the decomposition of hydrogen peroxide at all concentrations. For concentrations ~30% of HCl and ~30% H2O2 it gives Cl2, below some concentrations only O2 is liberated.
