A conjugate base is formed when an acid loses a proton (H+), whereas HB represents the acid in its protonated form. The conjugate base has one less proton than the acid HB.
In order to have an effective buffer, one needs to have a weak acid or a weak base, and the salt (conjugate) of that weak acid or weak base. Examples would be :weak acid/conjugate base: acetic acid/sodium acetateweak base/conjugate acid: ammonia/ammonium chloride
In a Brønsted-Lowry acid-base reaction, an acid donates a proton (H+) to a base, which accepts the proton. This results in the formation of a conjugate base from the acid and a conjugate acid from the base. The overall reaction involves the transfer of a proton from the acid to the base.
NH4+ is NH3's conjugate acid. NH3 accepts H+ to become a Bronsted-Lowry base.
In general, a buffer system can be represented by writing a salt followed by slash and an acid or conjugate base followed by slash and an acid like salt/acid or conjugate base/acid. Thus, the sodium acetate-acetic acid buffer system can be written asCH3COONa/ CH3COOH or CH3COO-/CH3COOHSimilarly, ammonia-ammonium chloride buffer system can be represented asNH3 / NH4+Note that NH4+ is an acid and NH3 is a conjugate base according to Lewry-Bronsted concept.
Acid + base conjugate base + conjugate acid
The conjugate base and conjugate acid for HS04 is: Conjugate acid is H2SO4 Conjugate base is SO42
The base which a certain acid turns into.Every acid had a conjugate base:HX (acid) X- (conjugate base)The acid is also called the base's conjugate acid.
If acid is strong then its conjugate base must be weak, if conjugate base is strong it again accept the H+ ions so acid can neither be strong, similarly if base is strong its conjugate acid must be weak.
NaHCO3 is a weak base, with a conjugate acid of H2CO3+.
The conjugate acid of H2O is H3O+ (hydronium ion). When an acid donates a proton, it forms its conjugate base, and when a base accepts a proton, it forms its conjugate acid.
Assuming you are asking about the base I-, the conjugate acid is HI, hydroiodic acid. Since hydroiodic acid is a strong acid, it can be concluded that iodide (I-) is a weak conjugate base.
The conjugate acid of the base NH2OH (hydroxlyamine) is NH3OH^+
The strength of a weak acid is inversely related to the strength of its conjugate base. If an acid is weak, its conjugate base will be stronger because the weaker the acid, the more easily it will give up its proton to form the conjugate base. Conversely, a stronger acid will have a weaker conjugate base.
The conjugate base results after the acidic hydrogen has been removed from the acid. For instance, if we look at water (a weak acid), then the conjugate base is the hydroxide anion, a strong base. The stronger the acid, the weaker the conjugate base, and vice versa.
In a chemical reaction, a weak acid and its conjugate base are related as a pair. When the weak acid donates a proton, it forms its conjugate base. The conjugate base can then accept a proton to reform the weak acid. They exist in equilibrium, with the weak acid and its conjugate base acting as partners in the reaction.
