Question

The number of ions formed when triamminetrichloro chromium (III) is dissolved in water :
(a) 2
(b) 3
(c) 1
(d) None of these

Answer 1

Answer:

correct answer is 0 ions. option d is correct.

Answer 2

The number of ions formed on dissolving triamminetrichlorochromium (III) ion in water is 0. The correct option is d) None of these.

• The formula of the triamminetrichlorochromium(III) ion is $[Cr^{III} (NH_{3} )_{3} Cl_{3} ]$

• The given compound is a complex salt. Complex compounds do not dissociate completely in water. It generally, retains the identity of the compound and only dissociates into simpler ions.
• The complex compound triamminetrichlorochromium(III) ion does not form any ions, as it maintains the identity of the complex on dissolving in water.

∴ The number of ions formed on dissolving triamminetrichlorochromium (III) ion in water is 0 and the option is d) None of these.
