Why is grape soft drink heterogeneous?

Grape soft drink is considered heterogeneous because it can contain various components that do not fully mix or have uniform distribution. For example, the presence of carbonated bubbles, pulp, or sediment can create distinct phases within the drink, making it visibly different in various parts. Additionally, if the drink contains added ingredients like fruit pulp or flavorings, these may not dissolve completely, resulting in a mixture that is not uniform throughout.
