Activity of the sodium-potassium pump. Variable permeability of the cell membrane for ions. Ions There are many ions in the cell and extracellular space, but not all of them can pass through the cell membrane.
WebFortunately, methods to estimate single ion activity and the activity of solutes are readily available. Activity is the "effective" concentration of an electrolyte or ion. Only the activity of a solute (salt) has thermodynamic meaning and only the activity of a solute can be measured unambiguously; however, we often need to understand the chemical WebBoth pH and ORP represent types of ion activity in liquids—pH measures hydrogen ion activity while ORP represents the potential transfer of electrons between chemicals or chemical compounds. Though measuring very different things, both pH and ORP share a close relationship and are often included together while discussing water quality.
