Apply the HumeRothery rules to determine which following sys

Apply the Hume-Rothery rules to determine which following systems would be likely to form unlimited solid solutions:

a) Al-Zn

b) Cu-Zn

c) Cu-Sn

d) Fe-C

e) Al-Ag

Solution

b) Cu-Zn(The solubility of a metal with higher valence in a solvent of lower valence is more compared when compared to others. so, Cu-Zn are best example for this case)
