Explanation:
Smaller atoms and stronger bonds promotes greater hardness in minerals.
Answer:
Explanation:
Materials used for sacrificial anodes must be relatively pure active metals.
Or we can say any metal with more negative potential that that of iron ( +0.59) is used for sacrificial anode for iron
so from the above the following can be used as sacrificial anode for iron
Mg = +1.06
Al = +0.96
Zn = +0.7
The following will not be used as sacrificial anode for iron because their negative reduction potential is less than that of iron ( +0.59)
Ag = -0.76
Cu = -0.44
Pb = 0
Sn = +0.34
Au = -3.05
