FAQs on The Ionization Constant of Water & pH Scale Video Lecture - Chemistry Class 11 - NEET
| 1. What is the ionization constant of water and how is it calculated? |  |
Ans. The ionization constant of water, also known as the dissociation constant, is a measure of the extent to which water molecules dissociate into hydrogen ions (H+) and hydroxide ions (OH-) in an aqueous solution. It is represented by the symbol Kw. The value of Kw at 25°C is 1.0 x 10^-14 mol^2/L^2. It is calculated by multiplying the concentration of H+ ions with the concentration of OH- ions in water.
| 2. What is the significance of the ionization constant of water in determining pH? | |
Ans. The ionization constant of water plays a crucial role in determining the pH (acidity or alkalinity) of a solution. By using the equation pH = -log[H+], the concentration of hydrogen ions (H+) in a solution can be calculated. Since the ionization constant of water is constant at a given temperature, any increase in H+ concentration will lead to a decrease in OH- concentration, and vice versa, thus affecting the pH of the solution.
| 3. How does temperature affect the ionization constant of water? | |
Ans. The ionization constant of water, Kw, is temperature-dependent. As temperature increases, the value of Kw also increases. This is because higher temperatures provide more energy for the water molecules to dissociate into ions. Therefore, at higher temperatures, water will have a higher concentration of H+ and OH- ions, resulting in a higher value of Kw.
| 4. What is the pH scale and how is it related to the ionization constant of water? | |
Ans. The pH scale is a measure of the acidity or alkalinity of a solution. It ranges from 0 to 14, with 7 being neutral. pH values below 7 indicate acidity, while values above 7 indicate alkalinity. The pH scale is logarithmic, meaning that each unit represents a tenfold difference in acidity or alkalinity. The ionization constant of water, Kw, is directly related to the pH scale. By using the equation pH = -log[H+], the concentration of H+ ions can be determined, which is influenced by the value of Kw.
| 5. How does the ionization constant of water affect chemical reactions in aqueous solutions? | |
Ans. The ionization constant of water serves as a fundamental parameter in various chemical reactions that occur in aqueous solutions. It determines the concentration of H+ and OH- ions, which can influence the rate and direction of chemical reactions. For example, the presence of H+ or OH- ions can catalyze certain reactions or act as reactants themselves. Understanding the ionization constant of water is crucial for predicting and controlling the behavior of chemical reactions in aqueous systems.
