Question
Identify from the list below the substance that will dissociate into ions.NaOH(aq)H2O(l)NaCl(s)Br2(aq)
Solution
The substance that will dissociate into ions from the list is NaOH(aq).
Here's the step by step explanation:
-
NaOH(aq): This is sodium hydroxide, a strong base that completely dissociates in water to form Na+ and OH- ions. The (aq) indicates that it is dissolved in water, which is necessary for the dissociation into ions to occur.
-
H2O(l): This is water. It does not dissociate into ions under normal conditions.
-
NaCl(s): This is sodium chloride in solid form. It does not dissociate into ions unless it is dissolved in water.
-
Br2(aq): This is bromine dissolved in water. It does not dissociate into ions because it is a covalent compound, not an ionic one.
So, the only substance in the list that will dissociate into ions is NaOH(aq).
