I am making up an electrolyte using the amounts shown in the formula, i.e. 1 level tablespoon of washing soda to 3.5 ounces of distilled water. However, the soda does not appear to be dissolving fully, even after several hours. Do I have to filter it, maybe, or should I expect it to be like this? My last attempt was made with warm water.

What brand is your washing soda? If its Arm and Hammer, then filter it through a coffee filter.

Kephra. I have now processed my own sodium carbonate from bicarb. Dissolves beautifully.

which sodium bicarbonate brand did u use ? And can u please write your bake process? I also tried to bake sodium bicarbonate at 210 C degree for about 1 hours and 15 minutes. It was wrapped to the aliminium foil at the baking.. But when i mix it with distilled water there was occur some white and big stones and they are not dissolve.. The reason is the sodium bicarbonate brand or the wrong baking process. Any idea?

Never process it in aluminum. You should use glass or stainless steel, preferably glass.
Just spread it out in the glass baking dish, and bake it at 200C for 30 minutes. Thats all thats required.

Mine took about a day or more for all the little bits to be completely dissolved. It eventually dissolved.

When I mix up electrolyte from homemade sodium carbonate from baking baking soda, it all goes into solution in a few minutes, not days. Something seems wrong here unless you're seriously mis-measuring and making a much higher concentration than you're thinking.
Try to warm the water some. That will increase solubility and aid in more rapid dissolution. Lukewarm is plenty.

That seems to be the same problem I was having when I tried to use A&H washing soda. Baked or straight out of the box. I was unable to get it to dissolve completely. And on top of that, it would still go milky in my dropper bottle after a few days. This happened even at the .6 molar levels. I cleaned & sterilized over and over. Finally the only solution was to just to bake the baking soda in a glass container. I have had no problems since then. I just use the washing soda for other things. I know have a 1 1/2 quart of ready to go baked baking soda.

I've never had that problem......the A&H washing soda just dissolves in dw with a little shaking.

Bobby: Did you use distilled water to dissolve your washing soda?

Kephra and Art,
I do use distilled water. I even used 2 other boxes to try to get it worked out, but no go. It still could have been some kind of contamination, on my part that I just happened to correct without realizing it. I do remember starting to boil and oven dry the dropper bottles and all my glassware around that time. But nothing ever helped the problem of it not dissolving.
