In aqueous solution, pentanoic acid (HC-H,02) dissociates to produce its conjugate base, the pentanoate ion (C5H,O2¯), and the hydronium ion (H,0*). The solution is at a temperature of 25°C. (a) If the K value of pentanoic acid is 1.5x10-5, calculate the K, value of the conjugate base. Kb = 49. (b) What are the corresponding pk, and pk, values for this conjugate acid-base pair? pka pkb 4.0 (c) How is pk, related to pk,? pK. ??? v pK = pK = 14.00 at 25°C
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.
