Sodium is the primary cation for ECF, potassium is the primary cation for ICF.
The most important cation is sodium.
The principal cation in extracellular fluid is sodium (Na^+) because it is present in the highest concentration (approx. 0.15 M).

Major Intracellular cation - K+ (Potassium) Major Extracellular cation - Na+ (Sodium) Major Intracellular anion - PO4+ (Phosphate) Major Extracellular anion - Cl- (Chloride)
Chloride is an Anion in Extracellular Fluid
cytoplasm
Extracellular is outside cells and intracellular is inside, so that extracellular fluid would not be inside cells.
The Chief Extracellular cation is sodium.

The acronym ECF stands for extracellular fluid. Extracellular fluid is the fluid outside of the cell in the human body.
