Question

for Cu^2+ and CO2 , which will behave as a Lewis acid towards OH- in water?

Answer 1

Cu^2+ will act as lewis acid towards OH^-
because Cu^2+ is an electron pair donater

Answer 2

Explanation:

Species which donate electrons are known as Lewis acid. Whereas species which accept electrons are known as Lewis bases.

When a neutral atom of copper looses two electrons then it occupies a +2 charge. Whereas carbon dioxide $(CO_{2})$ is a neutral compound as it has no charge.

Thus, $CO_{2}$ is neither lewis acid or base.

Hence, $Cu^{2+}$ will act as a lewis acid towards $OH^{-}$ in water.
