Answer» SOLUTION :(i)`B_2O_3, SiO_2, CO_2` it reacts with bases to form salts . It reacts with NaOH. `B_2O_3+2NAOH to underset"SODIUM metaborate"(2NaBO_2)+H_2O` `SiO_2+2NaOH oversetDeltato underset"Sodium silicate"(Na_2SiO_3) + H_2O` `CO_2 + 2NaOH to underset"Sodium carbonate"(Na_2CO_3) + H_2O` (ii) Due to amphoteric nature of both `Al_2O_3` and `PbO_2` they can react with both acid and base. `Al_2O_3 + 2NaOH to underset"Sodium meta aluminate"(NaAlO_2+ H_2O)` `Al_2O_3 + 3H_2SO_4 to Al_2(SO_4)_3 + 3H_2O` `PbO_2 + 2NaOH to underset"Sodium plumbet"(Na_2PbO_3) + H_2O` `2PbO_2 + 2H_2SO_4 to 2PbSO_4 + 2H_2O + O_2` (III) `Tl_2O_3` it reacts with acids to form salts . It reacts with HCl to form thallium chloride. `Tl_2O_3 + 6HCl to 2TlCl_3 + 3H_2O` |
