Morphine, C17H19O3N, is a weak base (Kb = 7.4 X 10-7) . Consider its titration with hydrochloric acid. In the titration, 50.0 mL of a 0.1500 M solution of morphine is titrated with 0.1045 M HCl.(a) Write a balanced net ionic equation for the reaction that takes place during titration.(b) What are the species present at the equivalence point?(c) What volume of hydrochloric acid is required to reach the equivalence point?(d) What is the pH of the solution before any HCl is added?(e) What is the pH of the solution halfway to the equivalence point?(f) What is the pH of the solution at the equivalence point?
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.
