Lewis base is a (n) a. producer of OH ions. b. proton acceptor. c. electron-pair donor. d. electron-pair acceptor. In the reaction represented by the equation Ag (aq) + 2NH3 (aq) - [Ag[ a. Bronsted-Lowry acid. b. Lewis acid

c. electron-pair donor.

Explanation:

Lewis base -

A Lewis base is an electron rich species, which is available for donation.

Hence, Lewis base is a electron - pair donor.

The indication of a Lewis base, is it has a negative charge or lone pairs of electrons.

Hence, the species with a lone pair or negative charge act as a Lewis base.

for example, OH ⁻ is a Lewis base, due to its negative charge which is available for donation.

H₂O is also a Lewis base, due to its lone pairs of electrons, that are available for donation.
