Question

Explain the parameters that affect the zeta potential. How zeta potential can be measured experimentally?​

Answer 1

Answer:

The zeta potential can be measured by this method for very small pore size and dense membranes where the pressure drop through the membranes is too high to investigate by transversal streaming potential measurements. ... In the EKA, the electrolyte solution is forced to flow through the measuring cell by means of a pump.

Answer 2

Explanation:

Explain the parameters that affect the zeta potential.

Ans The most important factor that affects zeta potential is the pH of the medium. Other factors include ionic strength, the concentration of any additives, and temperature. The significance of zeta potential is that its value can be related to the short- and long-term stability of emulsions.

How zeta potential can be measured experimentally?

Ans Zeta potential is measured by adding a solution to a cell that contains two gold electrodes. When a voltage is applied to the electrode, the particles will move toward the electrode with the opposite charge. A Doppler technique is used to measure the particle velocity as a function of voltage.
