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.

In a mixture of two acids that have similar K, values, the dissociation of one acid affects the dissociation
of the other acid, and vice versa. Prepare two ICE tables (where I means initial, C means change, and E
means equilibrium), one for the dissociation of HCHO2 and one for the dissociation of HC2H3O2.
Use the given acid-dissociation constants to calculate the amount of H3O+ produced by each acid in
the pair.
