Answer: NaOH can be classified as a strong base considering the ions it forms when it dissociates and its level of dissociation. The best option to answer the question is letter C.
Step-by-step explanation:
The question requires us to choose, among the options given, which one best describes sodium hydroxide (NaOH), knowing that this compounds completeley dissociates into positive and negative ions.
When NaOH dissociates, the ions Na+ and OH- are formed, according to the following dissociation reaction:
Since the dissociation of NaOH forms anions OH-, we can say it is a base. Also, since the dissocation of NaOH into its ions is complete, we can say that it is a strong base.
Therefore, NaOH can be classified as a strong base considering the ions it forms when it dissociates and its level of dissociation. The best option to answer the question is letter C.
