Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
![Many common weak bases are derivatives of NH3,
where one or more of the hydrogen atoms have been
replaced by another substituent. Such reactions can
be generically symbolized as
=
NX3(aq) + H₂O(1) ⇒ HNX3+ (aq) + OH(aq)
where NX3 is the base and HNX3+ is the
conjugate acid. The equilibrium-constant expression
for this reaction is
Kb =
where K₁, is the base ionization constant. The extent
of ionization, and thus the strength of the base,
increases as the value of K₁, increases.
K₂ and Ki are related through the equation
Kax Kb = Kw
As the strength of an acid increases, its Ką value
increase and the strength of the conjugate base
decreases (smaller K₁ value).
