In this way, ph is determined by hydrogen ion concentration . In the case of neutral solution [H+] =10-7 which we call a ph of 7. This means, for example, that a hydrogen-ion concentration of a solution with a ph of 4 is 10-4 mol/l, meaning it contains 0.0001 mole of hydrogen ion in a solution of 1 liter.
When water moves into an animal cell (e.g. a red blood cell), the cell membrane stretches and the cell gets bigger. If this continues, the cell membrane will burst – this is called lysis.
<u>Plant Cell</u>
When too much water moves out of a plant cell the cell contents shrink. This pulls the cell membrane away from the cell wall. A plasmolyzed cell is unlikely to survive.
