Part B
Is the reactant or product favored at equilibrium? (The p K
a
of ethyloxidanium is − 2.4.)

Correct
Equilibrium favors the formation of the weaker acid because a stronger acid tends to donate its proton to the weaker acid. Hydrochloric acid
(reactant) is a strong acid, and protonated ethyl alcohol or ethyloxidanium (product) is a weak acid, so the equilibrium will favor the product.

Identify each of the species in the following reaction:
Hint 1. Determining acids and bases and their conjugates
A base gains a proton (H
+
), forming its conjugate acid. An acid loses a proton, forming its conjugate base. See Section 2.1 ( Page 51 ) .
