Resistivity of Water - The Physics Factbook

Resistivity is an intrinsic property of a material that is measured as its resistance to current per unit length for a uniform cross section." Many people have conducted tests for this value for one reason or another (mostly for filtration systems) and have found the resistivity of water to be approximately 182,000 Ωm at 25 °C.

This activity coefficient is used in the calculation of the pH s (saturation pH) but it can also be used to determine the minimum concentration of a dissolved element required to be in equilibrium with its solid (salt) element. You can for example determine the minimum concentration of calcium that would be required in solution to be in equilibrium with the solid calcium carbonate.

Electrical Conductance Conductivity of Metal …

What is Conductance?When we apply same potential difference across different conductors, we will see different currents flow through them. Actually how much current will flow through a specific conductor for certain applied potential difference across it, depends upon a specific property of the conductor, called electrical conductance. This property determines…
