The charge balance equation is used to solve for a missing concentration of an ion. This neutrality equation is designed in a way where the molarity concentrations of cations along with their charge coefficients equal the molarity concentrations of anions and their charge coefficients. 

Description

The equation is 

eq1.png

or in summation form

eq2.png

where

  • ni is the ith species of cation charge coefficient
  • Ci is the ith species of cation molar concentration in units of (mol/L)
  • mi is the ith species of an anion charge coefficient
  • Ai is the ith species of an anion molar concentration in units of (mol/L)

*Notice: Both sides must equal each other, this equation was programmed so that the subtraction of cations from an anions was 0.
