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+

∙ 6y agoA 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+.”

∙ 11y agoThe 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+).

What scientists came up with the concept of conjugate acid-base pairs?
Gilbert N, Lewis
Is PO4 and HPO3 conjugate acid base pair?
No, the equation is: HPO4-2 → H+ + PO4-3 The HPO4-2 and PO4-3 are conjugate acid base pairs.
Give the products what acid base reactions and identify the conjugate acid base pairs NH3 H2O and NH4 CN?
NH3 + H20 <----> NH4+ + OH- Ammonia is a weak base so it is the favored side of the equilbrium. Conjugate acid and base pairs only differ by a proton. So ammonia and ammonium are pairs and water and hydroxide ions are pairs. NH4+ + CN- <-------> HCN + NH3
What is a characteristic of the Brønsted-Lowry definition of acids and bases?
acc. to this concept , acids are proton donor and base are proton acceptor . reverse of these reactions are also acid base pairs and the pairs are known as conjugate acid base pairs . .

A quadratic equation can't have one imaginary solution?
That's true. Complex and pure-imaginary solutions come in 'conjugate' pairs.
Which are conjugate acid-base pairs H2O and hf H2O and oh- hoci and oci- hi and you- koh and naoh?
HI and I- H2O AND OH- HOCl and OCI-
What is the zero pairs for the equation f(x)x2 plus 12 plus 6?
They are the complex conjugate numbers +/- 3*sqrt(2)*i where i is the imaginary square root of -1.
What is the conjugate acid of NO2-?
HNO2 conjugate acid = one more hydrogen conjugate base = one less hydrogen
What is the conjugate of 100?
"Conjugate" usually means that in one of two parts, the sign is changed - as in a complex conjugate. If the second part is missing, the conjugate is the same as the original number - in this case, 100.
