If the initial concentration of hydrochloric acid (HCl) in a solution is 0.01 M, what is the pH of the solution?
Given a weak acid solution with a pKa of 4.75 and a ratio of conjugate base to conjugate acid of 0.1, calculate the pH using the Henderson Hasselbalch equation.
A biochemist is studying a buffer system in blood with a pKa of 6.1. If the pH of the blood is 7.4, what is the ratio of bicarbonate (HCO3-) to carbonic acid (H2CO3)?
Calculate the pH of a solution with a pKa of 5.0 and a conjugate base to conjugate acid ratio of 0.5 using the Henderson Hasselbalch equation.
Evaluate the significance of the Henderson Hasselbalch equation in the context of cellular respiration.
A researcher is studying the effect of a drug on the pH of stomach acid, which has a pKa of 1.5. If the pH of the stomach acid is adjusted to 3.0, what is the ratio of the drug's conjugate base to conjugate acid?
