Apple juice has a lower ph than black coffee. which best explains the relationship?
a. apple juice has fewer hydrogen ions than black coffee.
b. apple juice has more hydrogen ions than black coffee.
c. apple juice has the same number of hydroxide ions as black coffee.
d. apple juice has more hydroxide ions than black coffee.

The answer to your question is letter B.

Explanation:

pH (Hydrogen potential) is a measure of the concentration of hydrogens in a solution. The scale goes from 0 to 14. Solutions with pH between 0 and 6.9 are acids, solutions with pH equal to 7 are neutral and solutions with a pH between 7.1 and 14 are bases.

Then, if a solution has a lower pH than another solution, it means that the first solution has a higher concentration of hydrogen ions.

the answer would be a
