Pyridine is a weak base that is used in the manufacture of pesticides and plastic resins. It is also a component of cigarette smoke. Pyridine ionizes in water as follows: C5H5N(aq)+H2O(l)⇌C5H5NH+(aq)+OH−(aq)C5H5N(aq)+H2O(l)⇌C5H5NH+(aq)+OH−(aq) The pKb of pyridine is 8.75. What is the pH of a 0.490 mol L−1 solution of pyridine? Express the pH numerically to two decimal places.
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.
C5H5N(aq)+H2O(l)⇌C5H5NH+(aq)+OH−(aq)C5H5N(aq)+H2O(l)⇌C5H5NH+(aq)+OH−(aq)
