An employer is interviewing 4 applicants for a job as a laboratory technician and asks each of them how to prepare a buffer solution with a pH close to 11.000. Use these ka’s to help you: Show your work Propionic Acid, CH3CH2COOH, ka = 1.34 x 10-5 Ethanamine, CH3CH2NH2, kb = 6.3 x 10-4 Jung says he would mix CH3CH2COOH & CH4CH3COOH Dominique says she would mix CH3CH2 NH2 & CH3CH2COOH Joshua says he would mix CH3CH2COOH & CH3COONa Kyla says she would mix CH3CH2NH2 & CH3CH2NH3Br Who would you hire based on their ability to make a buffer?
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.
