[pure-silver] Re: tank and tray cleaner

The designation 1N stands for 1 Normal.  For an acid solution it means that the
solution contains 1 mole of H+ ions per liter.  For a base like sodium hydroxide
it means 1 mole of OH-ions per liter.  A 1N solution of sulfuric acid contains
49 g/l of sulfuric acid.
