No, less liquid 1.0 molar solution electrolyte is needed to add the same amount of sodium carbonate to the solution.
As far as reducing agent goes, more does no harm, and since not everyone who buys a SilverTron is a member or reads the forum, I suggested values that are easy to remember, and gives the user the best chance of making perfect colloidal silver. There was someone here recently who was using a syringe to measure liquids, and it turned out that his syringe made 32 drops per ml instead of 20. See there is safety built into my instructions, especially for people who do not read this forum.
