Nomenclature
CAS number: 8007-31-6
Nitric acid silver (1+) salt mixt with silver chloride (AgCl); lunar caustic; molded silver nitrate.
Properties
Contains not less than 94.5% silver nitrate, remainder
is silver chloride. White or grayish, hard rods or thin small cones.
Darkens on exposure to light. Protect from
light.Caution
Potential symptoms of overexposure
by direct contact are tissue corrosion and burns; absorption through
mucous membranes or damaged areas of skin may be followed by systemic
toxicity (Humphreys).
