A metal A which is used in thermite process, when heated with oxygen gives an oxide B, whichis amphoteric in nature. Identify A and B. Write down the reactions of oxide B with HCl and NaOH. |
|
Answer» Solution :The metal A is ALUMINIUM AL. The substance B is `Al_2O_3`which is AMPHOTERIC because it reacts with both acid and base. `Al_2O_3 + 6HCl to 2Al_2O_3 + 3H_2O` `Al_2O_3 + 2NaOH to 2NaAlO_2 + H_2O` |
