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 you obtain the molar solubility of a compound from Ksp?
The equilibrium constant value of any insoluble or partially soluble compounds are known as Ksp i.e Solubility product.
The solubility product value of any compound can be used to find the molar solubility of the compound.
For example, lets take a compound PbCl2 with solubility product Ksp.
Hence the below steps to find the molar solubility of compound using solubility product.
1) Write the balanced solubility reaction of compound.
=> PbCl2 (s) -------> Pb2+ (aq) + 2 Cl- (aq) Keq = Ksp
2) Assume the molar solubility of compound is s and find the corresponding concentration of ions in the solution.
Since the molar solubility is s. Hence s concentration of compound will dissolve to product ions.
Since from the solubility reaction we can see that 1 molar concentration of PbCl2 will dissolve to produce 1 molar concentration of Pb2+ ions and 2 molar concentration of Cl- ions.
Hence the concentration of ions present in the solution at equilibrium will be,
=> [Pb2+ ] = s and [Cl- ] = 2s
