Abstract: This study investigated the relationship that exist between total dissolve solids (TDS) and electrical conductivity (EC) for mono-, di- and tri-valent metal compounds. Standard solution of soluble and ionizable representatives of these different valency metal compounds (NaCl, CaCl2, and FeCl2. 4H20) were prepared and there EC and TDS values were obtained at different concentrations with a suitable EC/TDS meter. Increase in EC and TDS values follows the trend, at 0.01M NaCl, EC is 1.4ms/cm, TDS is 0.8ppm. At 0.1MCaCl2, EC is 2.36ms/cm, TDS is 1.43ppm. At 0.1MFeCl2.4H20 EC is 2.36ms/cm, and TDS is1.57ppm. From the data obtained, mathematical model was established for the different valency metal compounds to state the relationship between EC and TDS. For each of the compounds an appropriate model to state the relationship are, for mono-valent metal compound NaCl, (EC = 0.052672+1.5025.TDS), di-valent metal compound, CaCl2 (EC= 1.072 + 131.TDS) and tri-valent metal compound, FeCl2. 4H20 (EC = 0.0251879 + 1. 49308 TDS) such that with a solution of such metal compound the value of EC or TDS can be approximately calculated and ascertained from the other.
