FAQs on Short Tricks: Degree of Dissociation Video Lecture - Chemistry Class 11 - NEET
| 1. What is the degree of dissociation? |  |
The degree of dissociation refers to the extent to which a compound dissociates or breaks apart into its constituent ions in a solution. It is represented by the Greek letter alpha (α) and is calculated as the ratio of the number of moles of dissociated particles to the initial number of moles of the compound.
| 2. How is the degree of dissociation calculated? | |
The degree of dissociation (α) can be calculated using the formula: α = (n - x) / n, where 'n' represents the initial number of moles of the compound and 'x' represents the number of moles of dissociated particles. This formula gives the ratio of undissociated moles to the initial moles.
| 3. What factors affect the degree of dissociation? | |
Several factors can influence the degree of dissociation of a compound in a solution. Some of the key factors include temperature, concentration of the solution, nature of the solute and solvent, and the presence of any catalysts or inhibitors. Generally, higher temperatures and lower concentrations tend to increase the degree of dissociation.
| 4. Can the degree of dissociation exceed 1? | |
No, the degree of dissociation cannot exceed 1. It is a ratio that represents the fraction of the compound that has dissociated into ions. Therefore, it can range between 0 and 1, where 0 indicates no dissociation and 1 indicates complete dissociation.
| 5. How does the degree of dissociation relate to conductivity? | |
The degree of dissociation is directly related to the conductivity of a solution. Higher the degree of dissociation, greater is the number of ions present in the solution, which leads to higher conductivity. In other words, a higher degree of dissociation indicates a stronger electrolyte and a higher ability to conduct electricity.
