Product description

  • To obtain Co2[Fe(CN)6] hydrosol, 12 ml of CoCl solution with a concentration of 0.006 N and 10 ml of K4[Fe(CN)6] solution with a concentration of 0.01 N were used.

Specify:

  • method and method for producing hydrosol
  • name of the components of the micelle of a given sol
  • ions that can be potential-determining in accordance with the Fayans-Peskov-Lipatov rule for a given sol (except for the micelles indicated in the formula)
  • what changes will occur in the system when a significant amount of CoCl2 is introduced (draw potential distribution curves)
  • in what ways can one determine the sign of the charge of a given colloidal particle?
  • based on the results of a study of the process of electrolyte coagulation of the sol:

electrolyte NaCl CaCl2 AlCl3

Cck, mol-eq/l 0.47 8.8*10-3 6.0*10-4

check the applicability of the Schulze-Hardy rule.
