What is meant by aqueous ? Give an example
queous is a term used to describe a system which involves water. The word aqueous is also applied to describe a solution or mixture in which water is the solvent. When a chemical species has been dissolved in water, this is denoted by writing (aq) after the chemical name.
Hydrophilic (water-loving) substances and many ior dissociate in water. Forionic compound dissolve example, when table salt or sodium chloride is dissolved in water, it dissociates into its ions to form Na+(aq) and Cl-(aq).
Hydrophobic (water-fearing) substances generally do not dissolve in water or form aqueous solutions. For example, mixing oil and water does not result in dissolving or dissociation. Many organic compounds are hydrophobic. Nonelectrolytes may dissolve in water, but they do not dissociate into ions and they maintain their integrity as molecules. Examples of nonelectrolytes include sugar, glycerol, urea, and methylsulfonylmethane (MSM). Properties of Aqueous Solutions Aqueous solutions often conduct electricity. Solutions that contain strong electrolytes tend to be good electrical conductors (e.g., seawater), while solutions that contain weak electrolytes tend to be poor conductors (e.g., tap water). The reason is that strong electrolytes completely dissociate into ions in water, while weak electrolytes incompletely dissociate.
