Diluent: solution used for diluting Stock solution to make the secondary and working solutions, usually water but could be a buffer of some sort or even organic solvents. Serial dilutions: a sequential set of dilutions in which the stock for each succeeding dilution is the working solution from the previous one.

Dilution. In the case of dilution (i.e., addition of pure water to your sample, or in natural systems, mixing of your stream, lake, or groundwater with meteoric water), the concentration of the conservative elements in this diluting water will be = 0. Therefore, set XB = 0. Therefore, from equation (3) XM = XA fA. or . XM = XA. WA/(WA + WB)
