In the reaction of aluminum bromide with ionized sodium bromide, which compound is the Lewis acid?

Explanation:

Such type of the chemical compounds or ions that has the ability to accept a lone pair of electrons or nonbonding pair of electrons are known as lewis acids such as aluminum chloride, aluminum bromide, and some other compounds and ions. Such type of the chemical species that can donate a pair of the elections is known as lewis bases such as ammonia, water, hydroxide ion, and some other chemical species. In the case of aluminum bromide,  aluminum has an empty orbital that can accept a pair of electron so this species behaves like lewis acid.
