Concentrated sulfuric acid (95-97%) is very reactive and dissolves most metals. Therefore, it is used in a variety of ways in refining precious metals. It does not dissolve gold but is great at dissolving metals like copper, silver, and iron so it may be useful in certain types of gold refining processes. Sulfuric acid is also a popular acid used in gold electroplating processes.
Sulfuric Acid is a strongly corrosive, dense, oily liquid and is colorless to dark brown, depending on purity. Miscible with water. It is a strong irritant to tissue.
CAUTION. Use great care in mixing with water due to heat evolution that causes explosive spattering. Always add the acid to water, never the reverse!
