Question

In which of the following is the number of hydrogen ions greater?
A) An alkaline solution
B) A basic solution
C) Blood
D) A solution with a pH of 6.2

Accepted Answer

A solution with a pH of 6.2 is more acidic than blood (which generally has a pH close to 7.4), alkaline solutions, and basic solutions (both of which have a pH above 7), meaning it has a greater concentration of hydrogen ions.
