How does adding a salt of the conjugate base of a weak acid (adding a common ion) affect the percent ionization of the weak acid in solution? O The percent ionization could either increase or decrease depending on the acid O The percent ionization could either increase or decrease depending on the ion O The percent ionization increases O The percent ionization remains unchanged O The percent ionization decreases
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.
![**Question:**
How does adding a salt of the conjugate base of a weak acid (adding a common ion) affect the percent ionization of the weak acid in solution?
**Options:**
- The percent ionization could either increase or decrease depending on the acid.
- The percent ionization could either increase or decrease depending on the ion.
- The percent ionization increases.
- The percent ionization remains unchanged.
- The percent ionization decreases.
**Explanation:**
This question explores the concept of the common ion effect in weak acid solutions. When a salt containing the conjugate base of the weak acid is added, it typically causes the percent ionization of the acid to decrease. This phenomenon occurs because the additional conjugate base from the salt shifts the equilibrium position, suppressing further ionization of the weak acid, thus illustrating Le Chatelier's principle.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F57117051-d013-4223-9396-a647a7daf985%2F2c175135-8566-4a5e-bee3-609faf4b5971%2Fubfhlqr_processed.jpeg&w=3840&q=75)
