Which has higher content of electrolytes, water or coconut water?
If by water you mean ordinary water out of the faucet that would have the most electrolyte. Since the liquid in a coconut is a mixture of water and carbohydrates, some of which are sugar this is a very poor electrolyte. On the other hand, if you are talking about distilled, pure water that has no electrolyte at all, probably the coconut would have more electrolyte in it.
