electrolyte solution

An electrolyte solution is a liquid that contains dissolved ions—charged particles like sodium, potassium, or chloride—that conduct electricity. These ions come from substances called electrolytes, such as salts, acids, or bases, dissolved in water. Electrolyte solutions are essential for maintaining the body's fluid balance, nerve function, and muscle activity. When electrolytes dissolve, they separate into positive and negative ions, allowing electrical signals to pass through the solution. This property makes electrolyte solutions useful in medical treatments, sports drinks, and batteries, where the flow of electric charge is important for function.
