Relation between the concentration of hydrogen and hydroxyl ions in an acidic solution:
In an acidic solution, the concentration of hydrogen ions (H+) is greater than the concentration of hydroxyl ions (OH-). This is because the solution has a higher concentration of H+ ions, which are responsible for the acidic properties.
Explanation:
1. Acidic solutions have a pH value less than 7, indicating a higher concentration of hydrogen ions compared to hydroxyl ions. The pH scale is a measure of the concentration of hydrogen ions in a solution.
2. In water, a small fraction of molecules dissociate into hydrogen ions (H+) and hydroxyl ions (OH-). This is represented by the equation: H2O ⇌ H+ + OH-
3. In an acidic solution, the equilibrium shifts towards the production of more H+ ions. This means that more water molecules dissociate to form H+ ions and OH- ions.
4. As a result, the concentration of H+ ions increases, while the concentration of OH- ions decreases. This leads to a higher concentration of H+ ions compared to OH- ions in an acidic solution.
5. The concentration of H+ ions determines the acidity of a solution. The more H+ ions present, the stronger the acid. In contrast, the concentration of OH- ions determines the alkalinity of a solution. The more OH- ions present, the stronger the base.
6. Acids can donate H+ ions, while bases can accept H+ ions. In an acidic solution, the excess H+ ions can react with other species, such as water molecules or other ions, to form various acid-base reactions.
7. It is important to note that the concentration of H+ ions and OH- ions in an acidic solution is not fixed and can vary depending on the specific acid and its concentration.
In conclusion, in an acidic solution, the concentration of hydrogen ions (H+) is greater than the concentration of hydroxyl ions (OH-). This is due to the higher concentration of H+ ions, which are responsible for the acidic properties of the solution.
