Explanation
## Step 1:Sodium hydroxide (NaOH) is a strong base, which means it dissociates completely in water. In this process, sodium hydroxide splits into sodium ions (Na^+) and hydroxide ions (OH^-).## Step 2:We need to pay attention to both the state symbols and the charges in superscript. When NaOH dissociates in water, the sodium ion (Na^+) and hydroxide ion (OH^-) are both in aqueous form (aq).## Step 3:We can represent this dissociation with the balanced chemical equation:
## Step 4:Looking at the given options, we see that the correct representation of this dissociation is:
