Word origin: Latin aqua (water) + solutus (dissolved) See also: The human body is capable of regulating growth and energy balance through various feedback mechanisms. A precipitate is a compound with a low solubility that often falls out of solution as a solid. Many organic compounds are hydrophobic. When a chemical species has been dissolved in water, this is denoted by writing (aq) after The word aqueous (which comes from aqua) means pertaining to, related to, similar to, or dissolved in, water. The word aqueous is also applied to describe a solution or mixture in which water is the solvent. "Aqueous" redirects here. It is comprised basically of a dissolving agent called solvent and the dissolving material called the solute. A solution is a homogeneous mixture of solvent and solute molecules. Reactions in aqueous solution may result in products that are soluble in water or they may produce a precipitate. Substances that are hydrophobic ('water-fearing') do not dissolve well in water, whereas those that are hydrophilic ('water-friendly') do. The solute then diffuses through the solvent until the concentration is equal in all parts of the solution. An aqueous solution is a type of solution wherein the solvent (dissolving medium) is water. Fizzy drinks, salt water etc. Definition noun, plural: aqueous solutions A solution wherein water is the dissolving medium or solvent Supplement Solution, by definition, is a type of homogenous mixture in which the particles of one or more substances are distributed uniformly throughout another substance. By using ThoughtCo, you accept our, How to Predict Precipitates Using Solubility Rules. When a chemical species has been dissolved in water, this is denoted by writing (aq) after the chemical name. Aqueous Solution Explanation. In this type of reaction, the cation from one reactant takes the place for the cation in the other reactant, typically forming an ionic bond. The content on this website is for information only. For example, a solution of table salt, or sodium chloride (NaCl), in water would be represented as Na+(aq) + Cl−(aq). Aqueous solutions often conduct electricity. Get to know the e.. An aqueous solution is a solution in which the solvent is water. Latest research supports possibility of cryopreservation, Max-Planck Researchers Unravel The Structure Of The Methane Forming Enzyme. The blood sugar level is regulated by two hormones. In order for a compound to dissolve, the attractive force between a part of the molecule and hydrogen or oxygen has to be greater than the attractive force between water molecules. As water is an excellent solvent and is also naturally abundant, it is a ubiquitous solvent in chemistry. An aqueous solution is a solution in which the solvent is water. Aqueous is a term used to describe a system which involves water. For example, mixing oil and water does not result in dissolving or dissociation. She has taught science courses at the high school, college, and graduate levels. All Rights Reserved, Regulation of Organic Metabolism, Growth and Energy Balance. Aqueous solution is water with a pHof 7.… The hominid family diversified from the apes around 6 to 8 million years ago. Examples of nonelectrolytes include sugar, glycerol, urea, and methylsulfonylmethane (MSM). Another way to think of it is that the reactant ions "switch partners". There may not always be a precipitate. It is mostly shown in chemical equations by appending (aq) to the rel evant chemical formula. Explanation of Aqueous in the largest biology dictionary online. Those strong electrolytes are substances that are completely ionized in water, whereas the weak electrolytes exhibit only a small degree of ionization in water. A solution wherein water is the dissolving medium or solvent. When writing the equations of aqueous reactions, it is essential to determine the precipitate. Solution, by definition, is a type of homogenous mixture in which the particles of one or more substances are distributed uniformly throughout another substance.
