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 leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
