Chapter 3, Problem 3B.2ST
Interpretation Introduction

Interpretation:

The temperature has to be calculated for the system that is heated for the overall increase in entropy.

Concept Information:

Change in entropy on heating at constant volume: the change in entropy when the temperature is changed from Ti to Tf. The greater the heat capacity of substance, the change in entropy increases by increasing temperature. A high heat capacity implies that a lot of heat is required to produce a given change in temperature must be more powerful than for when the heat capacity is low, and the entropy increase is correspondingly high.

ΔS=Cln(TfTi)

Where,

C is the heat capacity of a substance,

Tf is the final temperature of the system,

Ti is the initial temperature of the system.

A small artisanal cheesemaker is testing the acidity of their milk before it coagulates. During fermentation, bacteria produce lactic acid (K₁ = 1.4 x 104), a weak acid that helps to curdle the milk and develop flavor. The cheesemaker has measured that the developing mixture contains lactic acid at an initial concentration of 0.025 M. Your task is to calculate the pH of this mixture and determine whether it meets the required acidity for proper cheese development. To achieve the best flavor, texture and reduce/control microbial growth, the pH range needs to be between pH 4.6 and 5.0. Assumptions: Lactic acid is a monoprotic acid H H :0:0: H-C-C H :0: O-H Figure 1: Lewis Structure for Lactic Acid For simplicity, you can use the generic formula HA to represent the acid You can assume lactic acid dissociation is in water as milk is mostly water. Temperature is 25°C 1. Write the K, expression for the dissociation of lactic acid in the space provided. Do not forget to include state symbols.…
