Initial Buffer Solution:
- Initial pH: 5
- Volume: 1 litre
Adding Pure Water:
When the volume of the buffer solution is increased to 2 litres by adding pure water, the pH of the resultant solution will change. The pH of the new solution can be calculated using the Henderson-Hasselbalch equation:
pH = pKa + log([A-]/[HA])
Where:
- pKa is the negative logarithm of the acid dissociation constant of the weak acid in the buffer solution
- [A-] is the concentration of the conjugate base
- [HA] is the concentration of the weak acid
In this case, as pure water is added, the concentrations of both the weak acid and its conjugate base will decrease, but the ratio of their concentrations will remain the same. Therefore, the pH of the resultant solution will remain the same as the initial pH of 5.
Resultant Solution:
- pH: 5
Therefore, after adding pure water to the buffer solution, the pH of the resultant solution will remain at 5.
- Initial pH: 5
- Volume: 1 litre
