3. When an acid is neutralized by a base in the presence of phenolphthalein, a faint purple-pink color is observed at the end point; however, after a few minutes, the solution becomes colorless. a. What can you say about the solution when it has a faint purple-pink color? What must have changed about the solution for the color to go away? Assume that the phenolphthalein is still present. b. The cause of the change is the carbon dioxide that is in the air. Rising levels of CO₂ in the atmosphere pose serious concerns not only for the temperature of the earth, but also a process known as ocean acidification. What is ocean acidification, and why is it a concern?
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.
