GROUP 1B- Coinage metals

Copper

2nd best conductor of electricity and 3rd most malleable and ductile which is an essential trace element enhancing iron physiologic utilisation

Wilson’s disease

Cu toxicity

Penicillamine

Wilson’s disease antidote

CuSO4·5H2O Blue vitriol, Bluestone

preparation of Fehling’s and Benedict’s solution, fungicide, antidote for P poisoning

Cu citrate

8% ointment is used as astringent

(Cu(AsO2)2·Cu(C2H3O2)2 Cu acetoarsenite

aka Parrot green/Parris green; pigment, rodenticide & insecticide

Basic copper acetate

aka Verdigris, paint pigment, pesticide & fungicide

Cu hydrogen arsenite

aka Schelee’s/Schloss green: insecticide & fungicide

CuSO4·5H2O·CaO Bordeaux mixture

algaecide and fungicide for swimming pool

Green

Cu flame test

Reddish brown ppt

Cu Ferrocyanide Test

Silver

2nd most malleable metal, 2nd most ductile metal & best conductor of electricity with oligodynamic properties

Argyria

Silver poisoning

NSS

Argyria antidote

Silver nitrate

aka Lunar caustic Indelible ink, Lapiz infernalis and a keratolytic agent for warts removal

Silver nitrate (1% ophthalmic solution)

eyewash for newly born babies for treatment of gonorrhea

Ammoniacal AgNO3

used for Tollen’s test (silver mirror test)

AgNO3 0.5% solution

used in wet dressing treats third degree burns

Mild silver protein

Argyrol (19-25%) Ag (used as antiseptic for eyes)

Strong silver protein

Protargin (7.5 & 8.5%), the protein is partially hydrolyzed providing higher concentration of Ag resulting to a more irritating and bactericidal action for irrigation of urethra and bladder for treatment of gonorrhea

Dimercaprol

Gold toxicity antidote

Nuggets

refers to gold dust/free gold

sodium aurothiomalate and auranofin

Two most common Gold preparations

Zsigmondy

The protective action of different colloids is measured in terms of the ‘Gold number’ introduced by him

Zsigmondy Number of Gold

Defined as the number of milligrams of a hydrophilic colloid that will just prevent the precipitation of 10 ml of a gold sol on the addition of 1 ml of 10% NaCl solution
