an acid and a base that are the same except for an H+
-apex
An acid base pair which differ from each other by a single proton(H+ ion) is called a conjugate pair.
Eg. Acid Base
HCl Cl-
NH3 NH4+
H2O H3O+
A conjugate acid is formed when a base gains a positive hydrogen Ion (H+), and thus, having the ability to lose this ion becomes a weak acid. The opposite is true when forming a conjugate base, an acid loses a H+ ion and therefore is a base, as it is able to steal ions.
It is “The base formed when an acid loses an H+.”

Conjugate acid-base pairs differ by a single proton. For example, ammonia (NH3) is a base, and its conjugate acid is ammonium (NH4+). Another example is water (H2O) as a base, and its conjugate acid is hydronium (H3O+).
The Bronsted Lowry theory states that:
- All acids are substances which can donate protons (H+)
- Bases are substances that can accept protons.
some (like water) can accept and donate protons. These are called amphiprotic:
H2O + H+ --> H30+
H2O + NH3 --> NH4+ + OH-
If you have an equation like:
HNO3 + OH- --> NO3- + H2O.
Here, the HNO3 has donated an H+ ion to the OH- to make the OH- into H2O. The HNO3 therefore becomes NO3- because it has lost a hydrogen ion.
The conjugate (acid-base) pairs are H2O with OH-, and HNO3 with NO3-, and also NH4+ with NH3 because they are the ones which have been changed into each other.
Pairs will always differ just ONE proton (H+).
A pair of two species that transform into each other by gain or loss of electrons.

What scientists came up with the concept of conjugate acid-base pairs?
The concept of conjugate acid-base pairs was proposed by G. N. Lewis in 1923. Later, this concept was further developed by G. S. Hammond in 1955, who introduced the idea of considering the relative stability of the conjugate acid-base pairs.

What are examples of conjugate acid base pair?
Some examples of conjugate acid-base pairs are HCl and Cl-, H2O and OH-, NH3 and NH4+.
Which are conjugate acid-base pairs H2O and hf H2O and oh- hoci and oci- hi and you- koh and naoh?
Conjugate acid-base pairs are related by the transfer of a proton. The pairs are: H2O and OH- HOCl and OCl- HCl and H2O KOH and NaOH
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.
Do conjugate adid base pairs have similar chemical properties?
Conjugate acid-base pairs have similar chemical properties because they differ by a proton. The conjugate acid is formed by gaining a proton, while the conjugate base is formed by losing a proton. This shared relationship ensures that they have similar reactivity and behavior in chemical reactions.

Give the products what acid base reactions and identify the conjugate acid base pairs NH3 H2O and NH4 CN?
The products of the acid-base reaction between NH3 and H2O are NH4+ and OH-. The conjugate acid-base pairs are NH3/NH4+ and H2O/OH-. For NH4 and CN-, no acid-base reaction occurs as CN- is a weak base that won't react with NH4+.
A quadratic equation can't have one imaginary solution?
That's true. Complex and pure-imaginary solutions come in 'conjugate' pairs.
Is PO4 and HPO3 conjugate acid base pair?
Yes, PO4 and HPO3 are a conjugate acid-base pair. PO4 can act as a base to form HPO3, while HPO3 can act as an acid to form PO4. This is because they differ by a proton (H+).
What is the conjugate acid of cio- HCIO HCI CI- CIO?
The conjugate acid of ClO- is HClO. The conjugate acid of HClO is ClO2. The conjugate acid of HCI is H2Cl. The conjugate acid of Cl- is HCl. The conjugate acid of ClO is HClO2.
What is the zero pairs for the equation f(x)x2 plus 12 plus 6?
