  1. 1.

    During polymerization of aquo ions of Al(III), nitrate and chloride ions take part in the formation of sol particles, forming two types of bond, strong and weak. The weakly held anions are in a state of rapid exchange with free anions of the solution.

  2. 2.

    The ClO4 anion does not interact with the polymerization products of the aquo ions of aluminum.

  3. 3.

    The SO42− anion prevents the formation of hydroxo complex Al13O4 (OH)24 (H2O)127+ and promotes the formation of sol particles.

  4. 4.

    The broadening of the NMR lines of quadrupole nuclei in the anions and solvent is a sensitive indicator of the formation of sol particles in the solutions.
