Uncontaminated freshwater contains no salt ions and therefore has a low conductance range of 10-2,00 S/cm. These conductive ions come from The repulsive osmotic pressure leads to Learn about water treatment. If exceptionally high-purity water is required, double distilled water is used. TzS The saying was: "It takes one gallon of fuel to make one gallon of fresh water. Usually, the source water is boiled and the steam is collected and condensed to yield distilled water. Purified water is treated to remove chemicals and contaminants, but distilled water takes it one step further. This ability is directly related to the concentration of ions in the water 1. Until World War II, distilling seawater to produce fresh water was time-consuming and expensive in fuel. TDS or Total Dissolved Solids is a measure of the total ions in solution. WebHigh quality deionized water has a conductivity of about 0.05 S/cm at 25 C, typical drinking water is in the range of 200800 S/cm, while sea water is about 50 mS/cm [2] (or 0.05 S/cm). Explain.
