Question

A02- is the Lewisin the followingreaction.SO3(g) + 0²-(aq) → SO4²- (aq)B

Answer 1

Base

Explanations:

Given the reaction expressed as:

`SO_3(g)+O^(2-)(aq)\rightarrow SO_4^(2-)(aq)`

According to the lewis theory, lewis acid is an ion which accepts a pair of nonbonding electrons. According to the equation above we can see that the oxygen ion donate an electron pair to the central atom SO3 to produce SO4^2-, this makes the oxygen ion the lewis base.
