Soda water is an example of which type of mixture?

Soda water is an example of a homogeneous mixture because it consists of a uniform composition throughout. In a homogeneous mixture, the different components blend together so seamlessly that individual substances are not distinguishable by sight. In the case of soda water, carbon dioxide gas is dissolved in water, creating a solution where the gas is evenly distributed, making it difficult to differentiate between the components.

In contrast, a heterogeneous mixture would exhibit distinct layers or a variation in composition, where individual components can be seen and identified, such as in a salad or a mixture of sand and pebbles. An elemental compound refers to a pure substance consisting of the same type of atoms, while atomic structure relates to the arrangement of atoms in a molecule and does not apply to the classification of mixtures.
