A conjugate base is the species that forms when an acid donates a proton, while a conjugate acid is the species that forms when a base accepts a proton. They differ from their parent acid or base by one proton.
The conjugate base results after the acidic hydrogen (proton) has been removed from the acid.
The conjugate acid results after the base has picked up a proton from another stronger acid.
Conjugated pairs of acid and base always differ only one proton, and the stronger the acid, the weaker the conjugate base, and vice versa. (the stronger one is in 'bold' characters)
For instance, (acid and base couples, all in water solution)
HCl and Cl-, (chloride is very, very weak; weaker than H2O as base)
CH3COOH and CH3COO- (acatic acid and acetate),
NH4+ and NH3 (ammonium and ammonia),
H2CO3 and HCO3- (hydrous carbon dioxide (carbonic acid) and monohydrogen carbonate)
HCO3- and CO32- (monohydrogen carbonate and carbonate)
H3O+ and H2O (hydronium and water)
H2O and OH- (water and hydroxide)
CH3CH2OH and CH3CH2O-(ethanol and ethoxide anion or ethanoate, a stronger base than hydroxide!)
The conjugate base of an acid is the substance that remains after the acid has donated its proton.Example: Acid is HX and conjugate base is X^-.
Acid is HCl, conjugate base is Cl^-.
Acid is acetic acid (CH3COOH), conjugate base is acetate (CH3COO^-)

What best describes a bronsted lowry acid base reaction?
Acid + base conjugate base + conjugate acid
What is the conjugate base and conjugate acid for HSO4-?
The conjugate base and conjugate acid for HS04 is: Conjugate acid is H2SO4 Conjugate base is SO42
Explain how the relationship between the strengths of an acid and its conjugate base and of a base and its conjugated acid?
When an acid is strong, its conjugate base will be weak, and vice versa. Similarly, when a base is strong, its conjugate acid will be weak, and when a base is weak, its conjugate acid will be strong. This relationship is known as the principle of conjugate pairs in acid-base reactions.
Is the conjugate of a strong base is a weak acid?
No, the conjugate of a strong base is a weak acid. The conjugate base of a strong acid is weak, while the conjugate acid of a strong base is weak.
Conjugate acid of H2O?
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.
What best describes a bronsted lowry acid base reaction?
Acid + base conjugate base + conjugate acid
What is the conjugate base and conjugate acid for HSO4-?
The conjugate base and conjugate acid for HS04 is: Conjugate acid is H2SO4 Conjugate base is SO42
What is a congugate base?
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.
Explain how the relationship between the strengths of an acid and its conjugate base and of a base and its conjugated acid?
When an acid is strong, its conjugate base will be weak, and vice versa. Similarly, when a base is strong, its conjugate acid will be weak, and when a base is weak, its conjugate acid will be strong. This relationship is known as the principle of conjugate pairs in acid-base reactions.
Is the conjugate of a strong base is a weak acid?
No, the conjugate of a strong base is a weak acid. The conjugate base of a strong acid is weak, while the conjugate acid of a strong base is weak.
What is the general form for the simplest type of acid base reaction?
Acid + base salt + water
Conjugate acid of H2O?
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.
What is the conjugate base for acid Iodine?
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.
What is the conjugate acid of NH2OH?
The conjugate acid of the base NH2OH (hydroxlyamine) is NH3OH^+
How is the strength of a weak acid related to the strength of conjugate base?
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.
How does an base differ from its conjugate acid?
A base can accept a proton (H+) to form its conjugate acid, while a conjugate acid can donate a proton to form its corresponding base. The conjugate acid of a base will have one additional proton compared to the base, while the base of a conjugate acid will have one fewer proton.
