Describe what is meant by an equivalence point. When is it possible for an acid to have multiple equivalence points? What is the difference between an equivalence point and an endpoint?
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.
The equivalence point is the point in a titration where the amount of titrant added is enough to completely neutralize the analyte solution.
The endpoint of a titration is the point where the indicator just changes colour. The equivalence point is when the ratio of the reactants is in the amounts specified by the equation.
When a weak polyprotic acid is titrated, there are multiple equivalence points because the equivalence point will occur when an H + is dissociated. Therefore, the number of equivalence points depends on the number of H + atoms that can be removed from the molecule.
