You analyze for pyridine (Kü is approximately 10-⁹) by dissolving 0.1000 g of the complex in 100 mL of H₂O and titrating with a 0.01 M HCl solution. Which of the following indicators should be used to detect the endpoint? (Assume that the initial concentration of pyridine is approximately 0.01 M.) (A) thymol blue, pH range of color change = 8.0-9.6 (B) methyl red, pH range of color change = 4.8-6.0 (C) bromophenol blue, pH range of color change = 3.0-4.6 (D) bromothymol blue, pH range of color change = 6.0–7.6 (E) alizarin yellow, pH range of color change = 10.1-12.0
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.
