Thermal stability of metal oxides can be compared using electrochemical series. Explain. |
| Answer» Solution :Elements with higher standard reduction potential have lesser tendency of losing electrons. They are less electropositive and form OXIDES that are less STABLE towards heat. These metals are generally placed on the top in electrochemical SERIES when they are arranged in decreasing order of redcution potential `(+ve)` values and form unstable oxides towards heat, that is, these oxides are decomposed on heating. In case of weak electrolytes, DEGREE of dissociation increases with dilution. | |
