Question

An oxide of metal ‘X’ with valency 3 reacts with both acid HCl as well as base (a) Identify the metal ‘X’ and give the formula of its oxide. (b) Write the relevant chemical equation of metal oxide with acid as well as base.

Answer 1

➡️the metal oxide is Al2O3.....
➡️here Al is trivalent element....
➡️reactions of Al2O3 with acid and base are given below.....
⚫1️⃣reaction with acid...........
〰️2Al+6HCl+12H2O-------->2[Al(H2O)6]Cl3+3H3
hexa aqua aluminu(III)chloride

⚫2️⃣reaction with base.........
〰️2Al+2NaOH+6H2O-------->2Na[Al(OH)4]+3H2

⚫hope this helps......
