What name is given to a solution in which water is the solvent?

1. The solvent is the component present at the highest concentration. 2. When that component is water, the solution is called an aqueous solution. 3. Such solutions are very common on our planet. 4. A stock solution is a concentrated solution kept for later dilution, which is a different idea entirely. _Source: OpenStax Chemistry (CC BY 4.0), Ch 3 "Composition of Substances and Solutions", section 3.3 Molarity_
