I need help solving these **Lactic Acid Presence and pH Calculations****4. Lactic acid is found in milk and is present in human muscle tissue during exertion. It has also been found in the blood of a 16-year-old boy who survived prolonged exposure to carbon monoxide poisoning.** **a. Calculate the pH of a solution containing 0.75 M lactic acid (Kₐ = 1.4 x 10⁻⁴) and 0.25 M sodium lactate.** **b. Recalculate the pH after the addition of 0.05 ml of 0.1 M HCl. Compare this value with that where the same 0.05 ml of 0.1 M HCl is added to the equivalent amount of pH 7 water. You may assume no significant change in the volume since you are only adding 1 drop to each.**---### Explanation:- **Part a:** The problem involves calculating the pH of a buffered solution containing lactic acid and its conjugate base, sodium lactate. The acid dissociation constant (Kₐ) is given for lactic acid, and you need to use this information to determine the pH.- **Part b:** You will re-evaluate the pH after adding a small amount of hydrochloric acid (HCl). This part involves understanding how the pH of buffered and unbuffered solutions changes upon addition of a strong acid.This exercise helps reinforce concepts of acid-base chemistry, buffer systems, and changes in pH upon addition of acid.

4. Lactic acid is found in milk and is present in human muscle tissue during exertion. It has also been found in the blood of a 16 year old boy who survived prolonged exposure to carbon monoxide poisoning. a. Calculate the pH of a solution containing 0.75 M lactic acid (K₁ = 1.4 x 104) and 0.25 M sodium lactate. b. Recalculate the pH after the addition of 0.05 ml of 0.1 M HCl. Compare this value with that where the same 0.05 ml of 0.1 M HCl is added to the equivalent amount of pH 7 water. You may assume no significant change in the volume since you are only adding 1 drop to each.
