What is a base answer?
Apr 10, 2014. A base is a substance that results in an increase in the concentration of hydroxide ions when it is dissolved in water. For example, when NaOH dissolves, it results in the formation of Na1+ and OH1− ions.
What is a base and how does it form?
All definitions agree that bases are substances which react with acids as originally proposed by G. These ions can react with hydrogen ions (H+ according to Arrhenius) from the dissociation of acids to form water in an acid–base reaction. A base was therefore a metal hydroxide such as NaOH or Ca(OH)2.
What is the full meaning of base?
Acronym. Definition. BASE. Building, Antennae, Span, Earth (parachute jumping)
How is a base a base?
A base is a substance that can accept hydrogen ions (H+) or, more generally, donate a pair of valence electrons; a weak base does not, therefore, fully ionize or completely accept hydrogen ions in an aqueous solution. Bases increase pH; weak bases have a less dramatic effect on pH.
What is the definition of base in biology?
Definition. noun, plural: bases. (1) (molecular biology) The nucleobase of a nucleotide involved in base pairing, as of a DNA or RNA polymer. (2) (anatomy) The lowest or bottom part of a plant or animal organ closest to the point of attachment.
What do bases feel like?
Bases are another group of compounds that can be identified by their common properties. A base tastes bitter, feels slippery, and turns red litmus paper blue. The properties of bases are often described as the “opposite” of acids. Bases have many uses.
What is bases in science?
base, in chemistry, any substance that in water solution is slippery to the touch, tastes bitter, changes the colour of indicators (e.g., turns red litmus paper blue), reacts with acids to form salts, and promotes certain chemical reactions (base catalysis).
What definition best describes a base?
A base is also defined as a molecule that has the ability to accept an electron pair bond by entering another atom’s valence shell through its possession of one electron pair. There are a limited number of elements that have atoms with the ability to provide a molecule with basic properties.
What common foods are bases?
Acids and bases also occur naturally in most common food and animal products. Common acidic foods include citrus fruits, wine, yogurt with active cultures and most fermented foods and aged cheeses. Common alkaline–the more popular description for base substances–foods include bananas and milk.
What are 10 examples of bases that see use everyday?
Arrhenius Bases. Named for Swedish scientist Svante Arrhenius to describe base behavior in water,these bases dissociate when added to an aqueous solution,making them strong bases.
What is common use of bases?
A common use of bases is to reduce indigestion. Indigestion is cause by reflux or stomach acid, and the base magnesium hydroxide can be used to neutralise the acid and therefore cure indigestion.
