Nitric acid is commonly used to test for the presence of gold. Gold does not react with nitric acid, distinguishing it from other metals that may be present in a sample. However, please note that handling acids requires proper safety precautions, and it's essential to conduct such tests in a controlled environment.
'Aqua Regia'. which is a mixture of Nitric Acid and Hydrochloric acid. Gold will 'dissolve' in it.

nitric acid
Aqua regia , a mixture of one part nitric acid and three parts hydrochloric acid.
I'll assume you are asking about test acid. The test acid in gold test kits is nitric acid diluted to various strengths for use on different karat gold varieties. Here are a few scenarios to answer your question.Let's say you have a 14K gold ring. If you drip 14K acid on it, nothing will happen. If you drip 18K acid (or stronger) on it, the spot where the acid contacted it will turn brown. On the other hand, if the acid bubbles green, the ring is not actually gold at all.

Honey is not a reliable way to test gold. Most people use the scratch test and the acid test based on karats.
Well, the best way to test your silver is with silver acid, if in the acid test come very color red it is silver. But you can test with 18k acid for testing gold metal, if in the stone the line change blue color it is silver. But if you put silver acid in other white metal can be white gold and you see the line in the stone change yellow their have yellow gold inside or if it is red it is copper ! Wake up ! can be mix copper, yellow gold with Rhodium Plated. that in today's market their call commun artificial white gold plated! Sincerely: Profectional jewelry's!
Purity tests are used to determine the extent to which a particular substance is what is claimed. A classic purity test for gold is nitric acid; if the item being examined reacts to the acid it is not gold, or at least not pure gold.
