Is it true that under certain conditions, Mg can reduce Al_(2)O_(3)" and "Al can reduce MgO? What are those conditions? |
| Answer» Solution :Looking at the Ellingham diagram, we see that the curve of oxidation of Mg lies below the curve for oxidation af AL upto about `1270""^(@)C`. After that TWO CURVES CHANGE their positions. That is, the curve for Mg lies above the curve for Al. Therefore before the temperature `1270""^(@)C`, Mg can reduce `Al_(2)O_(3)` but above this temperature, Al can reduce MGO. | |
