what is the relationship between the number of ions present at pH 7 verses pH 8
the cytoplasm of a cell is at pH7 and the interior of an organelle is at pH8
Homework Answers
Answer- pH is the negative alogrithm of the hydrogen ions. The cytoplasm of the cell with pH 7 is neutral while the organelles with pH 8 is basic and has less number of hydrogen ions as compared to cytoplasm.
