In aluminum oxide (Al₂O₃), the oxidation number of aluminum (Al) is +3, while the oxidation number of oxygen (O) is -2. Since there are two aluminum atoms contributing a total of +6 and three oxygen atoms contributing a total of -6, the compound is electrically neutral, confirming these oxidation states. Thus, the oxidation numbers are +3 for Al and -2 for O.

What is the oxidation number of Al in Al2o3?
In aluminum oxide (Al₂O₃), the oxidation number of aluminum (Al) is +3. This is determined by considering that oxygen typically has an oxidation number of -2. Since there are three oxygen atoms contributing a total of -6, the two aluminum atoms must have a combined oxidation number of +6, leading to an individual oxidation state of +3 for each aluminum atom.

What are the oxidation numbers for AlOH-1?
In AlOH^1-, oxygen typically has an oxidation number of -2. Since the overall charge of AlOH^1- is -1, the oxidation number of Al can be calculated as follows: (oxidation number of Al) + (oxidation number of O) + (oxidation number of H) = -1. Solving for Al gives an oxidation number of +3.

Is 2AL2O3- 4AL 3O2 a redox reaction?
Yes, the reaction 2Al₂O₃ → 4Al + 3O₂ is a redox reaction. In this process, aluminum (Al) is reduced from its +3 oxidation state in Al₂O₃ to elemental aluminum (0 oxidation state), while oxygen (O) is oxidized from its -2 oxidation state in Al₂O₃ to molecular oxygen (0 oxidation state in O₂). The transfer of electrons between the aluminum and oxygen species characterizes it as a redox reaction.
