Weak base information

A weak base is a base that, upon dissolution in water, does not dissociate completely, so that the resulting aqueous solution contains only a small proportion...

solvent to transfer a proton to a reference solute (most commonly a weak aniline base) is measured by its Hammett acidity function, the H 0 {\displaystyle...

acid hydrogen chloride and the weak base ammonia. Conversely, neutralizing a weak acid with a strong base gives a weakly basic salt (e.g., sodium fluoride...

be considered. A weak acid or the conjugate acid of a weak base can be treated using the same formalism. Acid HA: HA ⇌ H+ + A− Base A: HA+ ⇌ H+ + A First...

technique is used for the purification of weak acids and bases. A pH indicator is a weak acid or weak base that changes colour in the transition pH range...

In mathematics, weak topology is an alternative term for certain initial topologies, often on topological vector spaces or spaces of linear operators,...

CH3(CH2)2NH2. It is a colorless volatile liquid. Propylamine is a weak base. Its Kb (base dissociation constant) is 4.7 × 10−4. Propyl amine hydrochloride...

bromothymol blue being most appropriate. Titrations between a weak acid and a weak base have titration curves which are very irregular. Because of this...

leavening process, agents (one or more food-grade chemicals—usually a weak acid and a weak base) are added into the dough during mixing. These agents undergo...

ion ([NH4]+). Although ammonia is well known as a weak base, it can also act as an extremely weak acid. It is a protic substance and is capable of formation...

with water. Like other amines, it is a weak base, compared to strong bases such as NaOH, but it is a stronger base than its aromatic analog, aniline. It...

on this enzyme. Antimalarials are lipophilic weak bases and easily pass plasma membranes. The free base form accumulates in lysosomes (acidic cytoplasmic...

over-powder wad, designed to improve the penetration abilities of the weak base cartridge. Barrel rifling: 6 grooves with a right hand twist (6-right)...

typically used to combine weak base learners (such as decision stumps), it has been shown that it can also effectively combine strong base learners (such as deep...

Oxazoles are aromatic compounds but less so than the thiazoles. Oxazole is a weak base; its conjugate acid has a pKa of 0.8, compared to 7 for imidazole. The...

pH dependent, and slightly alkaline conditions, achieved by adding a weak base, such as sodium salicylate, give a faster reaction and therefore produce...

than a square entity for base tables. An identifying relationship is one where the primary key is populated to the child weak entity as a primary key in...

production of hydrogen fluoride for fluorocarbons. Fluoride is classified as a weak base since it only partially associates in solution, but concentrated fluoride...

the compound. A common kind of hydrolysis occurs when a salt of a weak acid or weak base (or both) is dissolved in water. Water spontaneously ionizes into...

amine and a diol. Like other organic amines, diethanolamine acts as a weak base. Reflecting the hydrophilic character of the secondary amine and hydroxyl...

adjacent nitrogen atoms, which are in ortho-substitution. Pyrazole is a weak base, with pKb 11.5 (pKa of the conjugate acid 2.49 at 25 °C). Pyrazoles are...
