Ionivahvuus
Ionivahvuus, often translated as ionic strength, is a measure of the intensity of electric fields produced by ions in a solution. It is defined as half the sum of the products of the molar concentration and the square of the charge of each ion in the solution. Mathematically, it is expressed as I = 0.5 * Σ(ci * zi^2), where 'ci' represents the molar concentration of the i-th ion and 'zi' represents its charge.
The concept of ionic strength is crucial in understanding the behavior of electrolytes in aqueous solutions.
In dilute solutions, ions are relatively far apart, and their interactions are weaker. As ionic strength increases,
Ionic strength plays a role in diverse fields, including chemistry, biology, and environmental science. For example,
