Which of the following is an example of an interstitial solid solution?
Brass (Cu-Zn alloy)
Steel (Fe-C alloy)
Bronze (Cu-Sn alloy)
Amalgam (Hg-Alloy)
Amalgam, which is an alloy of mercury (Hg) with another metal, such as silver (Ag), gold (Au), or tin (Sn), is an example of an interstitial solid solution. In amalgams, the mercury atoms occupy the interstitial voids between the atoms of the other metal, forming a solid solution.
