_______ are substances which when dissolved in water will conduct an electric current.
A substance that dissolves in solution to conduct an electrical current is an electrolyte or, less commonly, an ionogen. View all chapters. 1  1. Ionic Bond Formation. 2  2. Ionic Compounds. 3  3.

Acids, for example, can ionize in solution to produce ions, which are free to conduct electric current. Certain polymers, with free electrons or multiple bonds can also conduct electric current. Aqueous solutions that conduct electric current efficiently contain strong electrolytes, while ones that conduct poorly are considered to have weak electrolytes. Those strong electrolytes are substances that are completely ionized in water, whereas the weak electrolytes exhibit only a small degree of ionization in water. Covalent compounds can be subdivided into polar and no polar compounds. In water, a polar molecule, the hydrogen electrons are not shared equally with the oxygen atoms; this results in a polar bond. Oxygen due to it's greater electro negativity pulls the electrons closer to its nucleus. An aqueous solution is a solution in which the solvent is water. It is usually shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, or sodium chloride (NaCl), in water would be represented as Na+(aq) + Cl−(aq). The word aqueous means pertaining to, related to, similar to, or dissolved in water. As water is an excellent solvent and is also naturally abundant, it is a ubiquitous solvent in chemistry. Substances that are hydrophobic ('water-fearing') often do not dissolve well in water, whereas those that are hydrophilic ('water-friendly') do. An example of a hydrophilic substance is sodium chloride. For example, a solution of table salt, or sodium chloride (NaCl), in water would be represented as Na + (aq) + Cl − (aq). The word aqueous means pertaining to, related to, similar to, or dissolved in, water. As water is an excellent solvent and is also naturally abundant, it is a ubiquitous solvent in chemistry. Substances that are hydrophobic ('water-fearing') often do not dissolve well in water, whereas those that are hydrophilic ('water-friendly') do. So typically, even though we think of ionic compounds or metallic compounds able to conduct electric current, there are some instances where covalently bonded molecular compounds can conduct electricity as well.

Reactions in aqueous solutions are usually metathesis reactions. Metathesis reactions are another term for double-displacement; that is, when a cation displaces to form an ionic bond with the other anion. Some do. Electrolytes, which are substances that break into ions when dissolved in water, will conduct electricity. Such substances include soluble salts, acids, and bases. Ot…her water soluble substances are non electrolytes and do not break into ions in water, or at least do so in extremely minute amounts.
Soluble salts, acids, and bases are substances which when dissolved in water will conduct an electric current.
