Relation between the concentration of hydrogen and hydroxyl ions in a basic solution:
In a basic solution, the concentration of hydroxyl ions (OH-) is greater than the concentration of hydrogen ions (H+). This can be explained by the concept of dissociation of water and the self-ionization of water.
1. Dissociation of water:
Water (H2O) can act as an acid and a base through a process called self-ionization. In this process, a small fraction of water molecules dissociate into hydrogen ions (H+) and hydroxyl ions (OH-).
H2O ⇌ H+ + OH-
The concentration of hydrogen ions and hydroxyl ions in pure water at 25°C is 1 × 10^-7 M each. This is because water dissociates into equal numbers of hydrogen and hydroxyl ions, resulting in a neutral solution.
2. Self-ionization of water:
In a basic solution, the concentration of hydroxyl ions is greater than the concentration of hydrogen ions. When an alkaline substance is added to water, it can increase the concentration of hydroxyl ions, leading to a basic solution.
For example, if sodium hydroxide (NaOH) is added to water, it dissociates into sodium ions (Na+) and hydroxyl ions (OH-). The hydroxyl ions contribute to the concentration of OH- in the solution, making it greater than the concentration of H+.
NaOH ⇌ Na+ + OH-
As a result, the concentration of hydroxyl ions is higher than the concentration of hydrogen ions in a basic solution.
Conclusion:
In summary, the correct answer is option B: The value of hydroxyl ion concentration is greater than the value of hydrogen ion concentration in a basic solution. This is because the addition of alkaline substances increases the concentration of hydroxyl ions, making the solution basic.
