An electrolyte solution is a liquid that contains ions, which are charged particles. These ions can conduct electricity, making the solution capable of carrying an electric current. Common examples of electrolyte solutions include saltwater, where sodium chloride (NaCl) dissolves into sodium (Na⁺) and chloride (Cl⁻) ions, and sports drinks that contain various electrolytes to help maintain hydration and balance in the body.
Electrolyte solutions play a crucial role in various biological and chemical processes. In the human body, electrolytes like potassium (K⁺), calcium (Ca²⁺), and magnesium (Mg²⁺) are essential for functions such as muscle contraction and nerve signaling. In industrial applications, electrolyte solutions are used in batteries and electrolysis, where they facilitate the movement of
