Tangy Electrolyte Water

I don't love drinking water, or at least not my own well water. I need a little something in it. Juice is good, but eventually I run out of juice, and the store is so far away. Here's a recipe for tangy electrolyte water. This would make, oh, enough powder for 8 twenty fluid ounce glasses at a sweet concentration like a gatorade, I think, or maybe 16 glasses at a half dilution if you just want to take the edge off of your well water.  

  18 tbsp sugar

4 tsp citric acid

2 tsp sodium chloride

1/2 tsp tripotassium citrate

Potassiun citrate tastes bad, and I'm just including it because it seems sporty. It's in sweat, so it makes sense to replenish it if you sweat. I did a half effort to figure out the mass ratio of elemental sodium to potassium in this as a sanity check and failed to get sensible numbers. I was hoping for like 4:1 or 5:1 sodium to potassium. I don't think the ratio of the ratio is too crazy. If I can't taste the potassum, can it really be too high? It tasted pretty bad on it's own. And there isn't really a bar of "too little potassium", since I'd normally be drinking water with none. So I think what I have is okay. But I'll try to do the correct calculation again soon.

I'm delighted to say that this recipe dilutes well. It doesn't taste unpleasant if you quarter your portion of powder, the way some sodas taste much worse after dilution. I also didn't mind this drink with a splash of Chopin vodka. So that's something to consider if you want some electrolytes and sugar with your recreational neurotoxins.

At some point I might try adding a small amount of posphoric acid, or some water soluble vitamins or something. But so far I'm very happy with this.

I couldn't find food grade potassium phosphate at a reasonable price. But if I had that, I'd use it in place of the potassium citrate, in order to keep things all powdered and not have to mess with phosphoric acid. I guess I could make my own potassium phosphate. But I want this recipe to be easy for other people to use.

I own a few other organic acids, but I'm pretty sure citric is the one I want to use. It's better on one dimension or other than acetic, malic, or fumaric acid
