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Many common weak bases are derivatives of NH3, where one or more of the hydrogen atoms have been replaced by another substituent.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 = [HNX,'][OH ] [NX3] where K is the base ionization constant. The extent of ionization, and thus the strength of the base, increases as the value of K₁, increases. K and K are related through the equation K₂ x Kb = Kw As the strength of an acid increases, its K₂ value increase and the strength of the conjugate base decreases (smaller K₁, value). If Kb for NX3 is 2.0x10-6, what is the percent ionization of a 0.325 M aqueous solution of NX3?
