- A solute is a substance in which is dissolved in another substance, the solvent. A common example used to explain this is using salt water; salt dissolved in water. In that case, salt is the solute and water is the solvent. Its really that simple. Solutes and solvents can exist in more than just solid-liquid (aqueous) solutions, as solutions can technically be in numerous phases.

4.1 General Properties of Aqueous Solutions Ions carry electrical charge from one electrode to another, completing the electrical circuit. Thus, the conductivity of NaCl solutions can be attributed to the presence of ions in the solution. A substance (such as NaCl) whose aqueous solutions contain ions and hence conduct electricity is called an electrolyte.

Aqueous solution The first solvation shell of a sodium ion dissolved in water. 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 NaCl(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.

humor aqueous humor the fluid produced in the eye and filling the spaces (anterior chamber and posterior chamber) in front of the lens and its attachments. It diffuses out of the eye into the blood and is regarded as the lymph of the eye, although its composition is different from that of the lymph in the rest of the body.

Chemistry symbols (aq), (l), (g), (s), what r they? Aqueous means it's in solution. For example, if you dissolve NaCl into water you would write NaCl(aq), but if you melted it until it was a liquid you would write NaCl(l). l = liquid, g = gas, and s = solid. They represent the state of the reagents in your reaction.

Nutrients and Solubility A very important solvent in nature and biology is water. Aqueous solutions are solutions containing water as the solvent. Many solutes can dissolve in water, and that is why water is the universal solvent. When a solution is formed, forces between particles in the solute and in the solvent are overcome. At the same time, new attractive forces are formed. The forces that are formed in a solution must be a similar strength as the forces overcome in the solute and solvent.

How to tell if compound (or element) is (aq), (l), (g), (s)? Best Answer: aq is aqueous, or dissolved in water. l is liquid. g is gas. s is solid. If it is below its melting point, then it is solid. If it is above its boiling point, then it is a gas. In between is a liquid and dissolved in water is aqueous. The following reaction occurs in water at room temperature: AgNO3(aq) + KCl(aq) → AgCl(s) + KNO3(aq) The reactants are soluble in water and are aqueous.

Acid An acid (from the Latin acidus/acēre meaning sour) is a chemical substance whose aqueous solutions are characterized by a sour taste, the ability to turn blue litmus red, and the ability to react with bases and certain metals (like calcium) to form salts.Aqueous solutions of acids have a pH of less than 7.s these examples show, acids can be solutions or pure substances, and can be derived from solids, liquids, or gases. Strong acids and some concentrated weak acids are corrosive, but there are exceptions such as carboranes and boric acid.

- There are a number of ways of telling whether something is an aqueous solution or some other liquid. 1. Is it transparent? If it's not, then it's not an aqueous solution. It may be a colloidal suspension, such as milk or paint. 2. Is it odourless? If it isn’t, it probably isn’t an aqueous solution.

Solvent A solvent (from the Latin solvō, I loosen, untie, I solve) is a substance that dissolves a solute (a chemically different liquid, solid or gas), resulting in a solution. A solvent is usually a liquid but can also be a solid or a gas.hen something is dissolved, molecules of the solvent arrange around molecules of the solute. Heat transfer is involved and entropy is increased making the solution more thermodynamically stable than the solute and solvent separately.

Acid An acid (from the Latin acidus/acēre meaning sour) is a chemical substance whose aqueous solutions are characterized by a sour taste, the ability to turn blue litmus red, and the ability to react with bases and certain metals (like calcium) to form salts.Aqueous solutions of acids have a pH of less than 7.Non-aqueous acids are usually formed when an anion (negative ion) reacts with one or more positively charged hydrogen cations. A lower pH means a higher acidity, and thus a higher concentration of positive hydrogen ions in the solution. strong acid is one that completely dissociates in water; in other words, one mole of a strong acid HA dissolves in water yielding one mole of H + and one mole of the conjugate base, A − , and none of the protonated acid HA.

Aquifer Typical aquifer cross-section. An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt) from which groundwater can be extracted using a water well.here are two end members in the spectrum of types of aquifers; confined and unconfined (with semi-confined being in between). Unconfined aquifers are sometimes also called water table or phreatic aquifers, because their upper boundary is the water table or phreatic surface.
