Are the ingredients in coke soluble or insoluble?

Answer 1

If you mean Coca-Cola, obviously they're soluble; if they weren't they'd settle to the bottom of the bottle and you'd have to shake it before drinking (note: shaking Coca-Cola before drinking is not recommended).

Answer 2

The main ingredients in Coke are soluble in water. This includes sugar (sucrose), various acids, flavorings, and colorings that dissolve in water to create the beverage. However, the carbon dioxide gas in Coke is insoluble and creates the fizzy bubbles.
