Abstract Composition, thermodynamic properties, and electrical conductivity of water plasma are calculated under the assumption of thermodynamic equilibrium. The plasma composition is calculated by stoichiometric approach in which chemical reactions and multiple ionizations are formulated by following mass action law and Saha's equation, respectively. Correction for weakly non‐ideal behavior at high density regime is conducted using the Debye‐Hückel theory. Based on the calculated composition, the electrical conductivities of water plasma, which is the most important parameter for various applications of pulsed spark discharges in water, are calculated at various mass densities and temperatures with the consideration of both electron‐neutral and electron‐ion collisions.
