The sodium is positively charged.
The chloride is negatively charged.
They cancel each other out and they create a salt crystal, right?
It's pretty chemically inert.
It's not that interesting.
But when you dissolve it in water...
then it dissociates and you get the electrolytes.
So these are now positively charged or negatively charged, and those charges on the ions within the water mean that your body can use them to do some really, really interesting biochemistry.
And just to kind of highlight what this means for our bodies, in fact, all living organisms.
Basically, we know that life evolved at the bottom of the sea, right?
And salt was eroded by the ocean from the rocks around the sea, and that gave rise to the fact that the sea is salty, right?
The life forms that were emerging at that time, they're little balls of fat.
Essentially, our cells have a lipid layer around them, lipids of fats, essentially.
And that's an excellent electrical insulator.
So what the cells learned was this trick of concentrating the sodium and the potassium ions either inside the cell or outside the cell.
What that does is it creates what's called an electrochemical gradient.
That gradient is essentially a biological battery, right?
So four billion years ago, the dawn of life on Earth, the cells basically created a way to harness electricity and use that for biology.
So that's why electrolytes are really important.
So just like you can use a battery to get a radio to work to make sound or get a torch to work to make light or whatever, a motor for motion.
