Nitric acid 70%,Nitrate acid
Nitric acid is a colourless highly corrosive mineral acid. Older samples however acquire a yellow cast due to decomposition into oxides of nitrogen.

Most commercially available nitric acid has a concentration of 68%.

Nitric acid is used as is in the digestion of wirewool where silver is NOT to be recovered together with gold since it dissolves most metals but gold. It dissolves the wirewool and many other metals through the following reaction.

2HNO3(aq) + M(metal) → H2(g) + 2MNO3(aq) / M(NO3)2


In acid digestion, nitric acid also helps deal with copper impurities in bullion which at low cyanide concentrations also tend to react with cyanide and thus cannot be separated before this stage.

Acid washing of carbon: HNO3 is also used in the acid washing of activated carbon for chemical regeneration.  Here the acid reacts with alkaline precipitates that coat and clog the carbon surface and micro-pores thus restoring its activity. A 5% solution is used for this application.

Other uses of nitric acid include:

  1. Production of fertilizers. Over 70% of the global nitric acid output is used to make ammonium nitrate
  2. Production of explosives for use in the mining  and construction industries
  3. Rocket propellant
