Crystals of silver nitrate under a microscope. Silver nitrate is an inorganic compound with chemical formula AgNO 3.It is a versatile precursor to many other silver compounds, such as those used in photography.
The position of equilibrium varies from base to base when a weak base reacts with water. The further to the left it is, the weaker the base. [5] When there is a hydrogen ion gradient between two sides of the biological membrane, the concentration of some weak bases are focused on only one side of the membrane. [6]
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. Due to their low solubility, some ...
Bases are defined by the Brønsted–Lowry theory as chemical substances that can accept a proton, i.e., a hydrogen ion. In water this is equivalent to a hydronium ion). The Lewis theory instead defines a Base as an electron-pair donor. The Lewis definition is broader — all Brønsted–Lowry bases are also Lewis bases.
Brønsted–Lowry acid–base reaction Brønsted–Lowry base Any chemical species that readily accepts a proton. Brownian motion Büchner flask buffered solution. Also simply called a buffer. An aqueous solution consisting of a weak acid and its conjugate base or a weak base and its conjugate acid that resists changes in pH when strong acids ...
That means that CsOH is equal to NaOH is equal to KOH. Ba(OH)2 is stronger, as are any strong bases that have two hydroxides. N.B. Not everything with a OH attached is a strong base, for example Mg(OH)2 is a weak base (and fairly insoluable to boot). one / zero 03:15, 25 July 2007 (UTC) Then why is Ba(OH) 2 listed as weaker than KOH?
Amphoteric is derived from the Greek word amphoteroi (ἀμφότεροι) meaning "both".Related words in acid-base chemistry are amphichromatic and amphichroic, both describing substances such as acid-base indicators which give one colour on reaction with an acid and another colour on reaction with a base.
On the other hand, if a chemical is a weak acid its conjugate base will not necessarily be strong. Consider that ethanoate, the conjugate base of ethanoic acid, has a base splitting constant (Kb) of about 5.6 × 10 −10, making it a weak base. In order for a species to have a strong conjugate base it has to be a very weak acid, like water.
