The pH of intracellular fluid is between roughly 6.8 and 7.4, depending on the tissue and cell type. This makes it slightly more acidic than extracellular fluid, which has a pH between about 7.3 and 7.5.
Here's a breakdown:
- Intracellular Fluid pH: 6.8 - 7.4
- Extracellular Fluid pH: 7.3 - 7.5
| Fluid Type | pH Range | Relative Acidity |
|---|---|---|
| Intracellular Fluid | 6.8 - 7.4 | More Acidic |
| Extracellular Fluid | 7.3 - 7.5 | Less Acidic |
The slight acidity of intracellular fluid compared to extracellular fluid is essential for various cellular processes.
