Question
Describe, what is conductivity of water? Explain, why conductivity of distilled water is very low Describe correlation between conductivity of water and TDS. Describe correlation between salinity and TDS. Here is a data of conductivity (specific conductance) for different concentration in M; (1M = 1 mol/L) of NaCl. Put those results in graphical form, (graph paper provided below) and assign units on x and y axes Find from the graph, what would be concentration of NaCl (in mol/L), when measured conductivity will be 5 mS/cm What would be estimated TDS in mg/L for this conductivity Recalculate obtained from the graph concentration from M (mole/L) to mg/LExplanation / Answer
1]
Conductivity of water is a capacity of water to pass electrical flow. It is directly proportional to the concentration of ions in water. The more ions that are present, the higher the conductivity of water. Likewise, the fewer ions that are in the water, the less conductive it is.
2]
In distilled water is lack of sufficient ions to conduct electrical flow. Distilled water is an insulator due to its very low conductivity value. Conductive ions come from dissolved salts and inorganic materials such as alkalis, chlorides, sulfides and carbonate compounds.

Correlation between conductivity of water and TDS
TDS is the solids dissolved in water. Dissolved salts and resulting ions conduct an electrical current. The more salts are dissolved in the water the higher is the value of the electric conductivity.
