Question

The particles present in the strong electrolytes are:

• A. Only molecules
• B. Mainly ions
• C. Ions and molecules
• D. Only atoms

Answer 1

The correct option is B

Mainly ions

Explanation:

Strong electrolytes: Strong electrolytes are those substances that completely dissociate into constituent ions in their aqueous solution.

Example: Sodium chloride

The dissociation of Sodium chloride can be represented as:

$\underset{\mathrm{Sodium}\mathrm{chloride}}{\mathrm{NaCl}\left(\mathrm{aq}\right)}\to \underset{\mathrm{Sodium}\mathrm{ion}}{{\mathrm{Na}}^{+}\left(\mathrm{aq}\right)}+\underset{\mathrm{Chloride}\mathrm{ion}}{{\mathrm{Cl}}^{-}\left(\mathrm{aq}\right)}$

Hence, the particles present in strong electrolytes are mainly ions.

Therefore, option (B) is correct.
