Question

Define the terms : (a) Helmholtz electrical double layer (b) Zeta potential

Answer 1

Hey mate

Here is ur answer by Lavanya Kumari

⭐Helmholtz electrical double layer is an double layer of positive and negative charges one molecule which occurs at the surface where two different materials are in contact.

⭐zeta potential is the potential difference between the dispersion medium and the stationary layer of fluid attached to the dispersed particle.

Answer 2

A) A Helmholtz double layer (HDL) is a structural representation of charge accumulation and separation that occurs at the meeting boundary of an electrode and an electrolyte. It exists primarily in fluid-based mixture systems, such as paints, and ceramic slurry used as a coating layer for corrosion prevention.



B) the potential difference existing between the surface of a solid particle immersed in a conducting liquid (e.g. water) and the bulk of the liquid.
