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.

Option B is the correct one.

Apple juice has more hydrogen ions than black coffee

Explanation:

An acid solution has higher [H⁺] and a lower [OH⁻]

pH = < 7

- log [H⁺] = pH

A basic solution has a higher [OH⁻], and a lowe [H⁺]

- log [OH⁻] = pOH

14 - pOH = pH

pH = > 7

For example Apple juice has [H⁺] =  0.03

pH = - log 0.03

pH = 1.52

Coffee has [OH⁻] = 0.03

pOH = 1.52

14 - 1.52 = 12.48 (pH)

Apple juice is more acid than coffee, thats why it has has more hydrogen ions than black coffee

B.) Apple juice has more hydrogen ions than black coffee.
