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.
How can we calculate the Molar Solubility in the Presence of a Common Ion?
To find: How can we calculate the Molar Solubility in the Presence of a Common Ion.
The molar solubility of any salt is defined as the concentration of salt that will dissolve in solution at equilibrium.
Since in the presence of any common ion, the reaction equilibrium of the solubility reaction will shift towards the reactant side.
Hence the molar solubility of the salt decreases in the presence of a common ion.
To illustrate how can we calculate the molar solubility of a salt in the presence of a common ion, let's understand the below example.
Example: In 0.0030 M ZnSO4 to calculate the molar solubility of Zn(OH)2.
Since in ZnSO4 solution, there will be ZnSO4 as well producing Zn2+ ions in the solution as ZnSO4 is completely soluble salt in water.
Hence there will be Zn2+ ions coming from ZnSO4 as well.
