Major Electrolytes Located Outside the Cell (Extracellular) Sodium and Calcium Sodium is a major electrolyte in extracellular fluid and it exercises most of its influence outside the cell. The concentration of sodium affects serum osmolality (solute concentration in 1 L of water) and extracellular fluid volume. Sodium also assists nerves and muscle cells to interact.
An electrolyte always contains a solute, which dissociates in the water to form ions.A strong electrolytes dissociate close to 100% or 100% in an aqueous solution. Weak electrolytes typically dissociate less than 10% in aqueous solutions. + 24 others found this useful. Dana Jurgens.
