i) It is a white lustrous metal.
ii) It melts at 1233°C and boils at 2485°C.
iii) Molten silver absorbs about twenty times its volume of oxygen which it again expels on cooling. Globules of molten silver are thrown off. This is called “spitting of silver”. This can be prevented by covering the molten metal with a layer of charcoal.
i) With dilute HNO3
Dilute HNO3 reacts with silver liberating nitric oxide.
3Ag + 4HNO3 → 3AgNO3 + NO↑ + 2H2O
ii) With con.HNO3 or con.H2SO4
Hot con.HNO3 or con.H2SO4 react with silver liberating NO2 and SO2 respectively.
Ag + 2 HNO3 → AgNO3 + NO2↑ + H2O
2Ag + 2H2SO4 → Ag2SO4 + SO2↑ + 2H2O
iii) Action with chlorine
Chlorine attacks silver, forming silver chloride.
2Ag + Cl2 → 2AgCl
iv) Action of alkalies
Silver is not attacked by alkalies.
