Question

The following pictures represent equal volumes of aqueous solutions of three acids HA (A = X,Y,or Z);water molecules have been omitted for clarity. 
-Arrange the acids in order of increasing acid strength.
A)HZ < HY < HX 
B)HY < HZ < HX 
C)HZ < HX < HY 
D)HX < HZ < HY

Quizplus · Accepted Answer

Acid strength increases with the ability of the acid to donate a proton (H+). This ability is influenced by the stability of the conjugate base formed after the proton is donated. If the conjugate base is more stable, the acid is stronger. Factors affecting this stability include electronegativity, size of the atom bonded to hydrogen, and resonance. Without specific information about HX, HY, and HZ, we cannot determine the exact reason for this order, but B) HY < HZ < HX is chosen based on the assumption that the question implies a specific context where HX is the strongest acid, followed by HZ, and then HY being the weakest.
