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...

and HCl are dissolved, the base and the acid neutralize exactly, leaving only NaCl, effectively table salt, in solution. Weak bases, such as baking soda...

with a strong base to form a neutral (pH = 7) solution. A strong acid will react with a weak base to form an acidic (pH < 7) solution. A weak acid will react...

with a weak base (e.g. sodium bicarbonate) to extract the strong acid, then washed with a strong base (e.g. sodium hydroxide) to extract the weak acid....

include a buffer solution. In a buffer, a weak acid and its conjugate base (in the form of a salt), or a weak base and its conjugate acid, are used in order...

concentrations of the weak acid to the weak base. The higher the concentration of the weak acid in the solution (compared to the weak base) the lower the resulting...

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...

orange, that changes color at low pH. When a weak acid reacts with an equivalent amount of a weak base, HA + B ⇌ A− + BH+ complete neutralization does...

involve them. With weak bases addition of acid is not quantitative because a solution of a weak base is a buffer solution. A solution of a weak acid is also...

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...

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...

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...

acid and a weak base, the result is an acid salt. If it is the result of a reaction between a strong base and a weak acid, the result is a base salt. If...

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

As perchlorate is a weak Lewis base (i.e., a weak electron pair donor) and a weak nucleophilic anion, it is also a very weakly coordinating anion. This...

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...

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

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...

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

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...

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

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...

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...

Brønsted–Lowry theory (also called proton theory of acids and bases) is an acid–base reaction theory which was first developed by Johannes Nicolaus Brønsted and...
