Question

define gold number and peptization​

Answer 1

Answer: The Gold Number is the minimum weight (in milligrams) of a protective colloid required to prevent the coagulation of 10 ml of a standard hydro gold sol when 1 ml of a 10% sodium chloride solution is added to it.

Answer 2

Answer:

The gold number is defined as the minimum mass of the colloid in milligram that is added to the 10ml of red gold sol to protect it from the coagulation when 1 ml of 10% NaCl is added.

Peptization is the process responsible for the formation of stable dispersion of colloidal particles in the dispersion medium. In other words, it may be defined as a process of converting a precipitate into a colloidal sol by shaking it with dispersion medium in the presence of a small amount of electrolyte.
