An ionic solution is a type of liquid that contains ions, which are charged particles formed when atoms gain or lose electrons. These solutions typically occur when ionic compounds, like table salt (sodium chloride), dissolve in water. The water molecules separate the ions, allowing them to move freely, which is essential for various chemical reactions. Ionic solutions are important in many fields, including chemistry, biology, and medicine. For example, they play a crucial role in biological processes, such as nerve signal transmission and muscle contraction. Additionally, ionic solutions are used in various applications, including batteries and electrolysis.
