Acids bases and salts A strong base is a basic chemical compound that can remove a proton (H+) from (or deprotonate) a molecule of even a very weak acid (such as water) in an acid-base reaction. Common examples of strong bases include hydroxides of alkali metals and alkaline earth metals, like NaOH and Ca(OH) 2, respectively.

"What Does the Scientific Term ""pH"" Mean?" The pH scale is made up of numbers from 0 through 14 and is used to determine whether a solution is an acid or a base. Numbers lower than 7 indicate acidity and numbers higher than 7 indicate alkalinity and indicate a base solution. A solution with a pH of 7 is neutral, a condition that is also known as pH balanced..

Nucleic Acid Each nucleotide includes one nitrogenous base, attached to the 1’ carbon of the sugar. A nitrogenous base is an organic molecule containing both carbon and nitrogen atoms. The name nitrogenous base signifies that several nitrogen atoms act as bases in solution. In nucleic acids, nitrogenous bases contain either one ring or two fused rings.

base 1 base definition. Any of a number of bitter-tasting, caustic materials. Technically, a material that produces negative ions in solution. A base is the opposite of an acid and has a pH of 7 to 14. A given amount of a base added to the same amount of an acid neutralizes the acid; water and a salt are produced.

pH In chemistry, pH (/piːˈeɪtʃ/) is a numeric scale used to specify the acidity or alkalinity of an aqueous solution. It is the negative of the logarithm to base 10 of the activity of the hydrogen ion. Solutions with a pH less than 7 are acidic and solutions with a pH greater than 7 are alkaline or basic. Pure water is neutral, being neither an acid nor a base. Contrary to popular belief, the pH value can be less than 0 or greater than 14 for very strong acids and bases respectively.

General Chemistry/Properties and Theories of Acids and Bases Cleaning products like bleach and ammonia are bases. Chemicals that are acidic or basic are an important part of chemistry. Several different theories explain what composes an acid and a base. The first scientific definition of an acid was proposed by the French chemist Antoine Lavoisier in the eighteenth century.

- - the amount of acid or base that is mixed with a certain amount of water. (a ratio of material to water), expressed as a weight or volume ratio. A strong acid or base will totally, or almost totally, ionize when mixed with water resulting in a. greater amount of H+ (acid) or OH- (base) ions.
