Respuesta :

Cranberry juice has more H ions in it as compared to the grape juice. Seven is the neutral pH. An increase in pH above 7 indicates an increase in alkalinity, whereas a fall in pH below 7 indicates an increase in acidity (hydrogen ions) (hydroxyl ions).

The concentration of hydrogen ions, or [H +], is represented by the pH scale, which is a logarithmic scale. In a logarithmic scale, such as the pH scale, a pH shift of 1 equates to a ten-fold change in the concentration of hydrogen ions. A solution with a pH of 5 contains 100 times more hydrogen ions than one with a pH of 7. A pH of 4 has a 1000-fold hydrogen ion concentration, while a pH of 3 has a 10,000-fold concentration.
