Ionic strength is a measure of the concentration of ions in a solution. It is an important parameter in histology because it influences various biological processes and interactions. The ionic strength of a solution affects the activity of enzymes, the stability of proteins, and the binding of molecules. It is calculated using the formula:
I = 1/2 Σ Ci Zi²
where _Ci_ is the concentration of the ion and _Zi_ is the charge of the ion.
