Note Set #1 – week 3: September 7 – 14 , 2016 Analytical Chemistry SYSTEMATIC TREATMENT OF EQUILIBRIA Charge balance, solutions have an overall neutral charge, therefore the negative ions must equal the positive ions the sum of all the negative charges must equal the sum of all the positive charges o If [P] is the conc. of a cation, [N] is the conc. of an anion, z is the absolute value, or magnitude of the positive charge, and y is the absolute value or magnitude of the negative charge, then: z [P ] + 1 [1 ] … 2 y2[N ] + y 1N ]1 2 2 o The magnitude of an ion’s charge becomes its coefficient in the eqn. Mass balance, all species that exist in the final solution must come from the original s
