What it is Filled
A homogeneous mixture in which one or more substances, the solutes, are dissolved in another, the solvent, at the molecular or ionic level, including aqueous solutions such as salt solutions and spirit vinegar, laboratory reagents such as lactophenol and viral transport media, and solid and gaseous solutions; solutions are described by concentration and are central to chemistry, biology, medicine and industry.
