NITRIC ACID
This acid is sometimes aqua fortis. Only the best and strongest acid should be used for dissolving silver to form the nitrate of silver. A small portion of it largely diluted with pure distilled water should form no cloud upon the addition of a drop of a strong solution of nitrate of silver. It should be kept in strong well stoppered bottles, in a dark, cool and dry place.
Care should be taken not to inhale any of the fumes that arise from the acid.
Should a drop of this or any other acid fall upon the clothes, apply freely and at once, a quantity of diluted aqua ammonia.
