Expert Solution

The following metals are used in costume jewelry

1) Pewter : It is metal alloy of Pb (Tin), Cu(Copper), Bi (Bismuth) and Sb (Antimony)

2) Sterling silver: It is alloy of Ag (silver),Cu (copper) now a days metalloid Ge (germenium) is added

3) Gold or Silver plated Brass : Brass is alloy of Cu(Copper) and Zn (Zinc)F

4) Base metals :Base metals are Fe (Iron),Ni (Nickel), Pb (Lead), Zn(Zinc)

5) Crystal, Zirconium dioxide(ZrO2) simulated to diamond

this inexpensive metals are coated with gold or silver by electrolysis process.the thickness of plating is about 2.5 to 20 microns

For silver plating silver rod and the metal (cosider iron jewelry) which is going to be coated placed in silver nitrate solution. Silver rod connected to anode of battery and jewelry connected to cathode end of battery.when electric current is passed through electrolyic cell silver undergoes oxidation Ag+ and will deposited on jewelry. jewelry looks like silver.

Gold plating is done by immersion method is based on displacement reaction where jewelry is immersed in acidic gold complex solution [Au(CN)2]. When this solution is heated about 90oC thin film of gold coated over jewelry.

In that way costume jewelry coated with gold or silver simulate the gold and silver they mimic.

An archaeologist finds some ancient jewelry made from bone. The jewelry has a carbon mass of 163 g (HINT: Assume all the carbon is 12C and determine the number of atoms) and careful measurements show that the remaining 14C has a current decay rate of 21 decays/s. Determine the age of the bone (and presumably the jewelry). Remember, the ratio of 14C to 12C when the animal died was 1.3×10-12 & the half-life of 14C is 5730 y. age of...
