Question

When aqueous solution of AICl₃ is concentrated, it furnishes crystals of ______.

विकल्प

• \[\ce{Al2Cl6 * 2H2O}\]

• \[\ce{AlCl3 * 2H2O}\]

• \[\ce{Al2Cl6 * 12H2O}\]

• \[\ce{Al2Cl6 * 24H2O}\]

Answer 1

When aqueous solution of AICl₃ is concentrated, it furnishes crystals of \[\underline{\ce{Al2Cl6 * 12H2O}}\].

Explanation:

In water Al³⁺ ion gets hydrated and exist as

\[\ce{[Al(H2O)6]Cl3}\]

i.e. \[\ce{AlCl3 * 6H2O  Or  Al2Cl6 * 12H2O}\]
