Hi,

I have a list of ingredients for an electrolyte drink that I buy and want to make it myself at home. I have a few questions if someone would be so kind as to help.

Sodium 276mg
Sodium Chloride 470mg
Potassium Chloride 300mg
Sodium Citrate Dihydrate 390mg
Contains Potassium 157mg
- Citric Acid Anhydrous 128mg
- Aspartame (E951)
- Dextrose Monohydrate 3.58g

Questions:
Why does it list Sodium? I don't think it can be bought in a form to consume, can it?

Is Sodium Citrate Dihydrate and Sodium Citrate the same thing?

If I made a batch of this at home, would I need to add Citric Acid Anhydrous?

Thanks,

James

We dont give receipies to  make medicine here.

But generally the sodium value is a summary  of all sodium compounds, so the potassium value.

The dehydrate contain 2 mol water of each mol of the citrate, so it is not the same reagarding the weight.

Thanks for you reply.

So, are you saying that the 470mg of sodium chloride is part made up of the 276mg of sodium listed?

"so it is not the same regarding the weight.", I'm not sure what you mean by this. Does Sodium Citrate Dihydrate have the same effect as Sodium Citrate? I did look up Sodium Citrate Dihydrate, and discover that it is made up of 2 mol water of each, but I still didn't know if with or without Dihydrate it still functions as a useful electrolyte.   

I only added the full list of ingredients to provide context for the question.

So, are you saying that the 470mg of sodium chloride is part made up of the 276mg of sodium listed?

Quite the opposite, part of the 276 mg sodium comes from 470 mg of sodium chloride.

Does Sodium Citrate Dihydrate have the same effect as Sodium Citrate?

Yes, but to prepare identical solutions you need different amounts.

Thank you, Borek, for the reply.

So, when they state there is 276mg of sodium, do they mean 276 mg of the total sodium chloride (470 mg) is Sodium? 

Yes, but to prepare identical solutions you need different amounts.

Could you explain this further please?

How much  Sodium Citrate do I need to use to recreate 390mg of Sodium Citrate Dihydrate ?

Thanks :-)

Dihydrate means crystalline form contains two molecules of water per each molecule of sodium citrate. When you weight such a solid you need to take this water into account and weigh more dihydrate than you would weigh anhydrous salt. Exact ratio can be easily found using molar masses.

Note: as long as you dissolve the salt in a small amount of water initially and then fill it up to the requested volume you don't need to worry about the presence of water in the context of the amount of solvent.

An electrolyte solution contains water, salt, potassium, and sugar in the proper concentration.

Homemade electrolyte solution

    1 liter of water.
    1 level teaspoon table salt.
    1 banana (blended in) -OR- 1 cup unsweetened orange juice.
