which of the combination of substances below constitute a Lewis acid-base reaction?
a) PH3+ H+
b) Ag+ + NH3
c) BF3 + NH3
d) CH3CH2OCH2CH3 +AlCl3
I'm stuck between a and b, but I am very confused because both seem to be lewis acids and bases to me

Acids are proton (H+) donors. Bases are proton (H+) acceptors. Acid-base reactions are often "reversible", meaning that they can occur in both a left-to-right and a right-to-left direction. As a result, there is one acid and one base on each side of an acid-base reaction. 1. Identify the Acids and Bases on both sides of the following reactions: a. NH4+ + OH- ⟷ NH3 + H2O b. HCl + H2O ⟷ Cl- + H3O+ c. H2PO4- + H2O ⟷ HPO42- ...
