Question

MEDAL & FAN ANYBODY ?
For the following reaction, identify one conjugate acid-base pair:
H2S04+H20>HS04+H30+
a. H2SO4 & H2O
b. HSO4- & H3O+
c. H2SO4 & HSO4-
d. H2O & HSO4-

Answer 1

In order to find the conjugate base of an acid, you take away a H.

In order to find the conjugate acid of a base, you add a H.


In the equation: HCl + NH3 -> NH4+ + Cl-

We can see that from NH3 to NH4+, a H is added because it goes from neutral to a charge of +1 (more protons than electrons).

We can also see that from HCl to Cl-, a H is removed because it goes from 2 H to 1 H. The charge itself goes from neutral to negative (more electrons than protons).


So we can say that NH3/NH4+ is the base conjugate acid pair, and
HCl/Cl- is the acid conjugate base pair.



this is an example
