Explain why potassium ion imbalances are less affected by water imbalances than sodium ions
What will be an ideal response?
Water imbalances can impact potassium ion concentration, but the effect is not as noticeable as with sodium ion concentration because fewer potassium ions are present in the extracellular fluid (ECF). Potassium ions are the most abundant intracellular cation.
