Question

A glass of grapefruit juice, at pH 3, contains _____ H+ ions than a glass of tomato juice, at pH 4.

A. More
B. Equal
C. Unable to answer based on information provided.
D. Fewer

Answer 1

A glass of grapefruit juice at pH 3 has ten times more hydrogen ions than a glass of tomato juice at pH 4.

Step-by-step explanation:

A glass of grapefruit juice, at pH 3, contains more H+ ions than a glass of tomato juice, at pH 4. The pH scale is logarithmic, meaning each whole pH value below 7 (the neutral point) represents a tenfold increase in hydrogen ion concentration. Since grapefruit juice has a pH of 3 and tomato juice has a pH of 4, the grapefruit juice has 10 times the concentration of hydrogen ions compared to the tomato juice. It is important to understand that acids like grapefruit juice can be harmful in excessive amounts, as they can erode tooth enamel and damage tissues.
