Diffusion in liquids and gases

Diffusion is the microscopic mass transport of particles due to concentration gradients. This trainer investigates the rate-limiting steps of diffusion in both aqueous solutions and gaseous phases.

• investigation of diffusion in liquids and gases
• transparent tank with magnetic stirrer, conductivity meter and U-tube with capillaries for investigating diffusion in aqueous solutions
• evaporation of a highly volatile solvent with a diffusion tube in a heated water bath for investigating diffusion in gases
• removal of gaseous solvent at the upper end of the diffusion tube with a fan
• heater with controller and sensor for adjusting the temperature in the water bath
• height-adjustable microscope for monitoring and determining the solvent volume in the diffusion tube
• separate display and control unit contains temperature display and fan
