Difference Between Liquid and Aqueous


Main Difference

The main difference between Liquid and Aqueous is that Liquid is a physical state of substance or matter that has no definite shape but has a certain volume whereas an aqueous is a mixture in which a substance liquefied in water.

Liquid vs. Aqueous

The liquid is a state of a substance that has no fixed mold but has a fixed capacity, size or volume, whereas an aqueous is a solution in which a matter disintegrated in liquid. All liquids are not an aqueous solution, but all aqueous solutions are liquids. The condition or term liquid denotes to any flowing or fluid that is almost in-compressible and squeezable, whereas the term aqueous denotes to the liquids which have water as the solvent. An immaculate or pure liquid has no solvent, but contaminated or impure liquids have a solvent that is whether organic or inorganic while aqueous solutions always contain water as the solvent. Liquids may comprise whether hydrophilic or hydrophobic solutes, whereas aqueous solutions always comprise hydrophilic solutes. For an organic equation, a liquid is used to specify the formation of liquid substances in a reaction. For example, when we burn Hydrogen in the air (Oxygen), and condense the resultant vapor or air, we get liquid water. While Aqueous’ in an organic equation shows that the substantial dispersed in water (a solution in water). For example, when we decant sodium hydroxide solution into diluted hydrochloric acid, we acquire an aqueous solution of sodium chloride.

What is Liquid?

A liquid is a specimen or state of a substance that imitates to the shape of a vessel in which it detained, and which attains a definite surface in the existence of gravity. The term liquid also provides about the state, or condition, of a substance having this quality. Liquids are almost in-compressible or compact liquids. Even under compression, their value only falls a little. Molecules or atoms in a liquid can transfer easily among each other. Liquids take the shape of their vessel. Though, a liquid cannot diffuse to fill a vessel. Liquids have inter-facial surface energy, which causes dampening. When two liquids sited into the same vessel, they may either be miscible or not be immiscible. Examples of two miscible liquids are water and ethanol. Oil and water are immiscible liquids. While liquids are common on Earth, liquids only exist or occur over a limited temperature and pressure array. When a liquid is intense or heated, the particles or molecules acquire kinetic energy. If the temperature converts are appropriately high, the liquid converts a gas, or it may react or respond with chemicals in the atmosphere. Water set an example of a liquid that turns out gaseous when it is heated steadily. When a liquid ventilated or cooled, the particles or atoms drop kinetic energy. If the temperature turns out rather low, the liquid converts a solid. Water is a fine example. If cooled or settled down, it freezes into ice.


What is Aqueous?

Aqueous means “much like,” “concerned,” or “liquefied in water.” An aqueous is any solution that utilizes water to dissolve or decompose a matter. That matter can be somewhat like sugar to turn sugar water, or dirt to turn mess we like to call mud. In aqueous solution, water is the solvent which is a liquid, and some other substance or compound which dissolved in it called the solute. There are two categories of matters or substances, one which purely dissolves in water, termed “hydrophilic,” and those who never dissolve or disband well in water, termed “hydrophobic.” Substances which liquefy in water titled “soluble,” and those which never liquefy titled “insoluble” and make a “precipitate” in place of an aqueous solution. Aqueous solutions are strong or solid electrolytes, which are capable of conducting electricity and are effective electrodes or conductors, whereas solutions about weak electrolytes or solutions are poor conductors of electrical energy. Matters that are good conductors are fully ionized in water, though reduced or poor conductors only illustration a small proportion of ionization. All aqueous solutions contain water as the solvent and are liquid in form. NaCl is the more commonly identified aqueous solution, where usual table salt is added to water to make a solution.


Key Differences

  1. A liquid is a physical form or state of the matter which has some classic or usual physical characteristics which differentiate it from other forms of the matter, whereas an aqueous is a solution wherever the solvent is water, which is a fluid or liquid, and some other matter or compound which dissolved in it termed the solute.
  2. So liquid it could be something else, e.g., oil. While an aqueous solution could it mean dissolved in water.
  3. A liquid can be either polar or non-polar, whereas an aqueous are always polar.
  4. An untainted liquid or pure liquid has no solvent, but contaminated or impure liquids have a solvent, while aqueous solutions at all times comprehend water as the solvent.


Though liquid and aqueous are completely dissimilar from each other and should not use interchangeably. The term liquid denotes to any fluid that is to say closely in-compressible, whereas the term aqueous denotes to the liquids which have water as the solvent.
