Although Coke/Dasani doesn't say what they are, they are in all likelihood simple salts like potassium chloride.
The start making Dasani by purifying tap water. Humans don't think very pure tap water tastes 'right' because they're used to drinking water that contains some level of dissolved salts (try taking a sip of highly distilled water or 'RO' water). So, they add some mineral salts to make the taste 'better'.
