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.
Draw the products of each reaction and determine the direction of equilibrium.
Generally for reaction which strongly favors product formation means then the base used to remove proton from acid should be stronger than base formed when the proton is removed. In a reaction which favors the products, equilibrium will favors the formation of the weaker acid or weaker base.
a)
The product obtained from given reaction is as follows,
The pKa of ethene is higher than the pKa of H2. On comparing the pKa value of an acid and the conjugated acid, reaction is always favorable towards the higher pKa value. Hence, in this reaction, equilibrium favors the reactants side.
b)
The product obtained from given reaction is as follows,
In the above reaction, the pKa value of water is less than methane. Hence, the equilibrium favors the reactants side.
