Chapter 14, Problem 27QAP
Interpretation Introduction

(a)

Interpretation:

The buffer capacity of 0.250 M lactic acid and 0.250 M lactate ion should be determined.

Concept introduction:

A buffer is a solution which resists change in pH on addition of small amount of acid or base. A buffer is prepared by mixing a weak acid with its conjugate base ion or a weak base and its conjugate acid ion.

For example the mixture of acetic acid and its conjugate base acetate ion will form a buffer solution.

The pH of a buffer solution is determined with the following equation

pH = pKa+log[salt][acid]

Also known as Henderson Hasselbalch’s equation

The buffer capacity is the capacity of a buffer to which it can resist a major change in pH on addition of acid or base.

It is dependent on the ratio of concentration of weak acid and concentration of its conjugate base.

Hello, I am doing a court case analysis in my Analytical Chemistry course. The case is about a dog napping and my role is prosecution of the defendant. I am tasked in the Area of Expertise in Neutron Activation and Isotopic Analysis.   Attached is the following  case study reading of my area of expertise! The landscaping stone was not particularly distinctive in its decoration but matched both the color and pattern of the Fluential’s landscaping stone as well as the stone in the back of the recovered vehicle. Further analysis of the stone was done using a technique called instrumental neutron activation analysis. (Proceed to Neutron Activation data)     Photo Notes: Landscaping stone recovered in vehicle. Stone at Fluential’s home is similar inappearance.   Finally, the white paint on the brick was analyzed using stable isotope analysis. The brick recovered at the scene had smeared white paint on it. A couple of pieces of brick in the back of the car had white paint on them. They…
