Water is not a good conductor of electricity; ultrapure water has a specific resistance of 18 MΩcm. The conductivity of water arises from the presence of ions, which are introduced through contamination. The discussion clarifies that while water lacks free electrons like metals, it is the movement of ions within the solution that facilitates electric current. Understanding the distinction between ionic conduction in water and electron conduction in metals is crucial for grasping the principles of electrical conductivity in aqueous solutions.
PREREQUISITESStudents in chemistry or physics, electrical engineers, and anyone interested in the principles of water conductivity and electrochemistry.
Yes,I know that ions makes water good conductor,but I don t understand the process of this.I metals are free electrons,but water not.And ions cannot be oxidise or reduce,because there aren t any electrodes like for example in the battery.So my question is,what exactly conducts electric current.Some graph or something will be welcome.THanks againBorek said:Water is not a good conductor, quite the opposite. Ultrapure water has a specific resistance of 18 MΩcm
Then, water gest very easily contaminated and it is presence of ions from contamination that makes it conductive.
