What does the host mean when he says that the acid has "donated a proton" to the water? A.

When hydrochloric acid is dissolved in water, a proton disappears in the chemical reaction.

B.

When hydrochloric acid dissociates, a positive hydrogen atom is accepted by water to form H₃O+.

C.

When hydrochloric acid dissociates, a negative hydrogen atom is accepted by water to form H₃O-.

What are the options? physical property can be color, smell, opacity, viscosity, density, infra red spectrum, melting and boiling points, attraction and repulson to magnets, etc.

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.
