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.
Calculate the molar solubility of Fe(OH)2 in pure water
The molar solubility has a direct relation with the solubility product. The solubility product of a substance is the number of moles of solute dissolved in per liter volume of the solution until the solution gets saturated ( means the maximum amount of solute is dissolved). Its unit of measurement is mol/l or M (molarity). For example,
The reaction of solubility of Fe(OH)2 in pure water is as-
Assume x be the molar solubility of Fe(OH)2 which gives x mol/l of Fe2+ and 2x mol/l of OH-.
The Ksp value of Fe(OH)2 is
Now, writing the solubility product relation with molar solubility for the above equation is as-
