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.

15. HCl is a strong acid, explain why when the pH is measured the pH of the acid sample is 5.4?
HCl is strong acid because it dissociates completely into H+ and Cl- ions means 100% dissociation when add into water.
At Equilibrium-
HCl(aq) ------> H+(aq) + Cl-(aq)
Acid Conjugate Base
At pH=5.4
we know,
pH = -log[H+]
[H+]= Anti(-5.4)
[H+]= 3.98 x 10-6 M
The formed conjugate base is stable because chlorine need one electron for complition of its octet,so it gain one electron from Hydrogen and atchive noble gas configuration and also stable like to noble gas. hence the gained electron can't revert back to H+ and both ion exist in ionic form at equilibrium.
