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.
Benzoic acid (C6H5COOH) and aniline (C6H5NH2) are
both derivatives of benzene. Benzoic acid is an acid with
Ka = 6.3 x10-5 and aniline is a base with Ka = 4.3 x10-10.
(a) What are the conjugate base of benzoic acid and
the conjugate acid of aniline? (b) Anilinium chloride
(C6H5NH3Cl) is a strong electrolyte that dissociates into
anilinium ions (C6H5NH3+) and chloride ions. Which will
be more acidic, a 0.10 M solution of benzoic acid or a 0.10
M solution of anilinium chloride? (c) What is the value of
the equilibrium constant for the following equilibrium?
C6H5COOH(aq) + C6H5NH2(aq) ⇌ C6H5COO-(aq) + C6H5NH3+(aq)
