When one mole of sodium chloride (NaCl) dissociates in water, it produces:

* One mole of sodium ions (Na+)

* One mole of chloride ions (Cl-)

The dissociation reaction looks like this:

NaCl (s) → Na+ (aq) + Cl- (aq)

Here's a breakdown:

* NaCl (s): Solid sodium chloride

* Na+ (aq): Sodium ions dissolved in water (aqueous)

* Cl- (aq): Chloride ions dissolved in water (aqueous)

This is why sodium chloride solutions are able to conduct electricity, as the dissolved ions can move freely and carry charge.
