Solution 1
To calculate the pH of a solution containing lactic acid and sodium lactate, we need to use the Henderson-Hasselbalch equation, which is:
pH = pKa + log([A-]/[HA])
Where:
- [A-] is the concentration of the base (sodium lactate in this case)
- [HA] is the concentration of the acid (lactic acid in t Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
