The quantity or abundance of a constituent of a mixture per unit quantity of the mixture; e.g. the amount of a dissolved solute per unit volume of the solution, a measure known as molarity. Several different definitions of concentration are widely used in chemistry, including mass concentration, volume concentration, and molar concentration.
Making a saline water solution by dissolving table salt in water.The salt is the solute and the water the solvent. In chemistry, a solution is defined by IUPAC as "A liquid or solid phase containing more than one substance, when for convenience one (or more) substance, which is called the solvent, is treated differently from the other substances, which are called solutes.
Concoction is the process of preparing a medicine, food or other substance out of many ingredients, and also the result of such a process. Historically, the word referred to digestion , as conceived by Aristotle who theorized that this was the result of the heat of the body acting upon the material, causing it to mature and ripen.
Opposite to covalent bonding, this chemical bond creates two oppositely charged ions. The metals in ionic bonding usually lose their valence electrons, becoming a positively charged cation. The nonmetal will gain the electrons from the metal, making the nonmetal a negatively charged anion. As outlined, ionic bonds occur between an electron ...
In physics and chemistry, a non-Newtonian fluid is a fluid that does not follow Newton's law of viscosity, that is, it has variable viscosity dependent on stress.In particular, the viscosity of non-Newtonian fluids can change when subjected to force.
Theriac or theriaca is a medical concoction originally labelled by the Greeks in the 1st century AD and widely adopted in the ancient world as far away as Persia, China and India via the trading links of the Silk Route. [2] It was an alexipharmic, or antidote for a variety of poisons and diseases.
It is thus the opposite of a synthesis reaction and can be written as [21] + One example of a decomposition reaction is the electrolysis of water to make oxygen and hydrogen gas: 2 H 2 O 2 H 2 + O 2 {\displaystyle {\ce {2H2O->2H2 + O2}}}
A solid solution, a term popularly used for metals, is a homogeneous mixture of two compounds in solid state and having a single crystal structure. [1] Many examples can be found in metallurgy, geology, and solid-state chemistry.
