There are many possible definitions ofmatter. In science, matter is the term for any type of material. Matter is anything that has mass and takes up space. At a minimum, matter requires at least one subatomic particle, although most matter consists of atoms. The wordmatteris sometimes used ...
In chemistry, the concentration of any species is denoted by writing it in square brackets. For example, [X] means “the concentration of X.” Given the above definition of pH, the fact that a proton is simply a hydrogen atom that has lost its only electron (H+), and using the square...
We can now calculate the pH value since we have the pOH of the solution. {eq}\rm... Learn more about this topic: Aqueous Solutions | Definition, Properties & Examples from Chapter 16/ Lesson 9 67K Learn what an aqueous solution is in chemistry. Understand how an aqueous solution differs...
Which of the following acids is strongest? a. H2Te b. H2O c. H2S d. H2Se What is the definition of a diprotic acid? What are the six strongest acids in general chemistry? Which of the following is a weak acid? a. HCl b. HNO_{3} c. H_{2}SO_{4} d. HBr e. H_{2}CO_{...
Concentration Definition In chemistry, concentration refers to the amount of a substance in a defined space. Another definition is that concentration is the ratio ofsolutein a solution to eithersolventor totalsolution. Concentration is usually expressed in terms ofmassper unitvolume. However, the solu...
In the early 1900s, an alternate definition for acids and bases was proposed by Johannes Brnsted and Thomas Lowry to account for the fact that ammonia can neutralize the acidity of HCl even if water isn't present. This phenomenon showed them that ammonia is a base, even when there isn't...

. A more technical definition of an alloy is 'a partial or complete solid solution of one or more elements in a metallic matrix'. Common examples of alloys include bronze, brass and steels. When alloys are specified, the specification often includes the ratios of the different metals in that...
Chemistry is the branch which deals with the detailed study of matter, its properties, how and why atoms/substanced combine or separate to form other substances. Understand all the basic concepts of Organic, Inorganic, and Physical Chemistry with detaile
Each conjugate acid-base pair has a specific pH range in which it functions as a buffer. On either side of the conjugate acid’s pKa, the buffering zone is around 1 pH unit. When one-half of the acid reacts to dissociation and the concentration of the proton donor (acid) equals th...
