Is coke a suspension or a colloid?

Answer 1

Coke is primarily a solution and not a suspension or a colloid. It contains dissolved sugars, acids, and flavor compounds in water, which means its components are fully dissolved and not suspended. However, when it comes to the carbonation in coke, the carbon dioxide gas can create a temporary foamy structure, but this does not classify it as a colloid or suspension in the traditional sense. Overall, the majority of coke is a homogeneous solution.
