b. Write a short note on the electrical conductivity of water?
Answers
Answer:
Electrical conductivity is denoted by the Greek letter ρ. This ability of conductance in water is directly proportional to the concentration of the ions present in the water. The Compounds which dissolve into the ions are known as the electrolytes
Ocean waters have water electrical conductivity of about 5 mS, tap water has EC in the range of 50 to 800 uS, depending on the source, freshwater streams may fall in the range of 100 to 2000 uS and distilled water has EC of between 0.5 and 3 uS. EC is relative to temperature.
Salinity and conductivity measure the water's ability to conduct electricity, which provides a measure of what is dissolved in water. In the SWMP data, a higher conductivity value indicates that there are more chemicals dissolved in the water. Conductivity measures the water's ability to conduct electricity.
