* Solvent: Water (H₂O)
* Solute: Carbon Dioxide (CO₂)
Explanation:
* Solvent: The solvent is the substance that dissolves the other substance. In soda water, the majority of the mixture is water, making it the solvent.
* Solute: The solute is the substance that gets dissolved. In this case, carbon dioxide gas is dissolved in the water to create the fizz and carbonation.
Key point: While soda water often has added flavors, these are typically very small amounts and are not considered the primary solute. The main reason soda water is different from plain water is the dissolved carbon dioxide.
