Salt Test
swrd:
Here are some samples... 500 milliliter beaker were used to make ionic silver. Then divided into 100 mililiters to make metalic silver.
İn order of ===> 1(heat) 2(1/10 dw/glucose syrp 1 drop) 3(1/1 deionized w/glucose syrp 1 drop) 4(150 mg maltodextrin) 5(1/10 deionized w/glucose syrp 1 drop then added 20 mg vegetable gelatine).
Added 1/4 tsp rock salt and stirred. :D Sorry for bad english and inexperience.

OP ?
swrd:
İt was a salt test for capping agents. All of these has good yellow color before adding salt. ??? Did i get it wrong? Im sorry if this is the wrong board for my topic.
Thanks for the answers.

So if I understood correctly, all of those samples that appear as clear water or almost clear water used to be yellow and then you added salt to them to test them and then they turned clear? The reason you did this was to test to see if they were capped? I would say that none of your samples were capped and were only reduced from ionic silver to colloidal silver so when you added the salt to the reduced colloidal silver, you basically destroyed it since there was no actual capping agent used in your process that I could see.

My purpose was to show the reaction of capping agents with salt. Reducers and herbal gelatin has weak protection but animal gelatine (no picture above) is useful. I couldn't find a picture of the topics related to salt reaction in the forum. I took a picture of samples because of this reason. Sorry for bad english. I get support from google translate.
