How is a solution referred to in short form?

A solution is often referred to by the term "sol," which is a shorter version of the word, typically used in scientific and medical contexts. This term emphasizes the homogeneous mixture of solute and solvent, which is essential for understanding the nature of solutions in various applications, such as medication preparations.

In contrast, the other terms provided do not specifically denote a solution. "Liquid" describes the state of matter but is too broad to specifically refer to a solution; it encompasses all liquids. The abbreviations "tab." and "cap." refer to tablet and capsule forms of medication, respectively, which are solid dosage forms and do not represent a solution. Thus, "sol" appropriately captures the essence of what a solution is in a concise manner.
