e) Provide the chemical equilibrium that describes the carbonic acid buffer system that exists at pH 9.3. Clearly indicate the chemical formulas, identify the weak acid and its conjugate base and the names of the chemical compounds.
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.
e) Provide the
f) Calculate the ratio of conjugate base/ weak acid at pH 9.3. Show all details of your working out for each individual mathematical manipulation that you apply (skipping steps will receive a deduction). In each step of your working out use the chemical formulas of the compounds that constitute the weak acid and conjugate base. Provide the answer to 3 decimal places, and make sure to round the result accordingly. State the final answer in a complete sentence
g) Calculate the concentration of the weak acid and conjugate base for a total buffer concentration of 150 mM at pH 9.3. Show all details of your working out for each individual mathematical manipulation that you do apply (skipping steps will receive a deduction). In each step of your working out use the chemical formulas of the compounds that constitute the weak acid and conjugate base. Provide the final answer to 3 decimal places using the unit molar ‘M’, make sure to round the result accordingly. State the final answer in a complete sentence.
