I asked one of my teachers about the best formula, so he gave me the following formula:
125ml deionized water
40 g Glacial Acetic Acid
40 g Citric Acid (lemon acid)
10 g Stannous Chloride
10 mg p-Aminophenol
40 g Sodium Hydroxide
water —-> 250ml
But he does not remember very well the dilution rate.
He also does not remember the life of the stock solution, nor the life of the work solution.
- I am confused ,,
This formula is designed on the basis of a quarter of a liter only.
I can double the quantities until one liter is reached.
But what is the rate of dilution in all cases (whether in the case it remained a quarter of a liter or if the quantities are doubled in order to reach one liter)?
After we know the dilution rate,
What is the optimum time ,, one minute or two minutes ,, and what is the optimal temperature?
- If we assume that I want to use the process (AP41) that operates at a temperature (21 ° C) in that case, how many minutes is this step supposed to be?
Is (working solution) used for one shot or what?
Finally, is this really the ideal formula or are there better formulas that live a long life?
I hope to listen to your suggestions and I will be grateful to all of you, God bless you
- I do not want to use the light bulb method, please do not and I will not accept that method.
