Explanation / Answer

15) For shrimps, [H+] = 0.0000001 M = 1.0*10-7 M and pH = -log [H+] = -log (1.0*10-7) = 7.0.

For bananas, [H+] = 0.00001 M = 1.0*10-5 M and pH = -log [H+] = -log (1.0*10-6) = 6.0.

Since bananas have a lower pH than shrimps, hence, bananas are more acidic. This is due to the fact that the lower the pH of a substance, the more is the release of protons from the substance. Consequently, the substance can supply more protons. A proton is acidic; hence, the higher the concentration of protons, the more acidic is the substance.
