A scale shows colors from red to purple with labels from the red end of 0, 1 gastric acid, 2 lemon juice, 3 orange juice, 4 tomato juice, 5 black coffee, 6 urine, 7 distilled water, 8 sea water, 9 baking soda, 10 milk of magnesia, 11 ammonia, 12 soapy water, 13 bleach, 14. Familiar solutions can have a wide range of pH levels.

According to the chart, which is the strongest acid, based on its pH level?
gastric acid

Lemon juice has approximately how many more times the H+ ions than tomato juice?
ten times

Which has the highest concentration of H+ ions: baking soda, ammonia, or bleach?
baking soda

Sorry i dont understand the question can you rephase it?

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.
