To optimize the processes of obtaining high-purity arsine and elemental arsenic by the electrochemical method, the dynamic viscosity is calculated and the kinematic viscosity is measured in solutions of arsenic acid formed by the electrolysis of a solution of hydrolytic sodium arsenite, the main product of the destruction of lewisite, in a temperature range of 20–80°C and a wide concentration range of 20–74 wt %.
