The stability of metal colloids obtained by Bredig's arc method can be enhanced by:
Diluting the colloidal solution with a non-polar solvent.
Adding acids to neutralize the colloid's charge.
Reducing the concentration of the metal salt.
Treating the colloidal solution with heat.
The stability of metal colloids prepared by Bredig's arc method can be enhanced by adding acids to the colloidal solution to neutralize the charges on the metal particles, reducing the likelihood of aggregation.
