WebBuffers: pH, Capacity and Ionic Strength! pH: The negative logarithm of the hydrogen ion concentration, the pH, is expressed as follows: . pH = -log 10 [H +]. The pH scale is a measure of hydrogen ion concentration that eliminates dealing with large powers of 10 and compresses a large range of concentrations onto a more convenient scale, between 1 … WebThe formula for calculating ionic strength (I) in any solution is where ci is the molar concentration of each individual ion, and zi is the charge of each ion. Example 6.16 Determine the ionic strength of a 0.10 M solution of MgCl2 at pH 7.0. The concentrations of each ion in this solution are [Mg 2+] = 0.10 M [Cl −] = 0.20 M [H +] = 1.0×10 −7 M
Webwhere I (or μ) is the ionic strength, c is the molar concentration of the ion and z its charge.
