Is it true that you can tell if water is clean by its electrical conductivity? [Basic Knowledge]

The more ions there are, the easier it is for electricity to flow? Tips for assessing water quality numerically!

■What does electrical conductivity represent? Electrical conductivity is a value that indicates how easily electricity flows through a substance. The more ions that are dissolved in water, the easier it is for electric current to flow, resulting in a larger value. ■How is it different from resistivity? Conversely, resistivity is an indicator that represents how difficult it is for electricity to pass through. Water with fewer ions is less conductive, so the value of resistivity increases. Electrical conductivity and resistivity are essentially two sides of the same coin. ■Why can water quality be determined by electrical conductivity? Many impurities found in natural water are electrolytes that become ions such as calcium and sodium when dissolved in water. Therefore, a higher electrical conductivity indicates a higher concentration of impurities, while a lower conductivity suggests fewer impurities. This property is utilized to easily assess the amount of impurities in water quality management.
