Which of the following is/are true when a weak acid HA is dissolved in water? I. It will form a dynamic equilibrium, where [HA] is equal to [A-] II. H3O+ ions will be formed. III. The solution’s pH will increase. IV. Adding OH- ions will shift the equilibrium to the left. a. III, and IV b. I Only c. I and II d. II Only
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.
