2016-1-5 · The overall mass balance equation is: m1+ m2= m3 The total solids balance equation is : m1x1+ m2x2= m3x3 The total water balance equation is : m1(1-x1) + m2(1-x2) = m3(1-x3) The total water balance equation is however NOT a totally new equation. It can be obtained by subtracting the total solids balance equation from the overall mass balance

Consider another example, that of dissolving sodium acetate in water to make up a 0.10 M solution. We can write two mass balance expressions. [Na +] = 0.10 M. Remember that the sodium acetate will dissociate into its component ions. The sodium ion does not undergo any reaction with water, but acetate does to produce acetic acid.
