Answer
Dissociation of $KCl$ in water:
$KCl(s) -^{H_2O}- \gt K^+(aq) + Cl^-(aq)$
Work Step by Step
- When strong electrolytes are added to water they dissociate, which means that they will divide, producing their ions.
1. Identify the cation and the anion in $KCl$
- Cation : 1 $K^+$
- Anion: 1 $Cl^-$
2. Write the equation for the dissociation:
$KCl(s) -^{H_2O}- \gt K^+(aq) + Cl^-(aq)$
** Remember, the ions are dissociated in an aqueous solution, so, their state symbol is "(aq)".
