[pure-silver] Re: HC 110 question ...

Georges, the simplest way to handle HC-110 is to use the recommended Kodak procedure of diluting the syrup 1:3 with water to make a stock solution and then dilute the stock solution 1:7 for Dilution B. The stock solution keeps well in glass. Use something like 100 mL of syrup and 300 mL water. Use the dilution water to dissolve and rinse the residual syrup out of the measuring container. A little bit of stirring helps. A 3X rinse with water should give a quantitative transfer of the HC-110. Rinsing the container for measuring the stock solution with the dilution water assures that all the active chemistry is in the working solution.
