FAQs on IONIC EQUILIBRIUM QUESTIONS - Additional Documents & Tests for IIT JAM

1. What is ionic equilibrium?
Ans. Ionic equilibrium refers to the state of balance between the ions and the molecules in a chemical reaction. It occurs when the rate of formation of products is equal to the rate of formation of reactants. In this state, the concentration of ions remains constant over time.
2. How is ionic equilibrium different from chemical equilibrium?
Ans. Ionic equilibrium specifically refers to the equilibrium involving ions, while chemical equilibrium is a broader concept that includes all types of chemical reactions. Ionic equilibrium focuses on the balance between the concentrations of ions and molecules, while chemical equilibrium considers the balance between the concentrations of all species involved in a reaction.
3. What are the factors that affect ionic equilibrium?
Ans. Several factors can affect ionic equilibrium, including temperature, concentration of reactants and products, pressure (in case of gaseous reactions), and the presence of catalysts. By changing these factors, the equilibrium position can be shifted, resulting in changes in the concentrations of ions and molecules.
4. How can we calculate the degree of ionization in a solution?
Ans. The degree of ionization, denoted by α, represents the fraction of total molecules that dissociate into ions in a solution. It can be calculated by dividing the concentration of ions by the initial concentration of the electrolyte and multiplying the result by 100. The formula is given as α = (concentration of ions / initial concentration of electrolyte) * 100.
5. What is the importance of ionic equilibrium in chemical reactions?
Ans. Ionic equilibrium is crucial in understanding and predicting the behavior of chemical reactions. It helps in determining the extent of a reaction, calculating equilibrium constants, and predicting the products of a reaction. Additionally, the concept of ionic equilibrium is essential in various fields like pharmaceuticals, environmental chemistry, and biochemistry, as it aids in understanding the behavior of ions in different chemical systems.
