Apple juice has a lower ph than black coffee. which best explains the relationship? 1. apple juice has fewer hydrogen ions than black coffee. 2. apple juice has more hydrogen ions than black coffee. 3. apple juice has the same number of hydroxide ions as black coffee. 4. apple juice has more hydroxide ions than black coffee.

2. Apple juice has more hydrogen ions than black coffee.

Explanation: pH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

Thus as pH and are inversely related, a solution having lower pH will have more amount of concentration. And a solution having more pH will have less amount of concentration.

Thus apple juice having lower pH than black coffee will have more concentration of hydrogen ions.

girl imma just put my comment here because i need a couple point okurrttt

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.
