What is the concentration of H+ ions at a pH = 7? mol/L
Calculate the ratio of H+ ions to OH-ions at a pH = 7.
Find the concentration of H+ ions to OH-ions listed in
Table B of your Student Guide. Then divide the H+
concentration by the OH concentration. Record this
calculated ratio in Table A of your Student Guide.
Compare your approximated and calculated ratios of H+
ions to OH-ions at a pH = 7. Are they the same? Why or
why not? Record your comparison in Table A.

A) the enthralling of formation for pure element in its standard state is always positivehope this : )

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.
