Interpretation Introduction
Interpretation:
From the Boyle’s law, Charles law, Avogadro’s Law the ideal gas equation should be explained
Concept Introduction:
Boyle’s law: According to Boyle’s law, pressure and volume are inversely proportional to each other at a given temperature.
PV=Constant ...(1)or Vα1P
Where,
P = Pressure
V = Volume
Charles law: According to Charles law, temperature and volume are directly proportional to each other at a constant pressure.
VαT(ataconstantpressure) ...(2)orVT=C
Where,
T = Temperature
V = Volume.
Avogadro’s law: According to Avogadro’s law, equal volumes of gases contain same number of molecules at a given temperature and volume.
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.

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.…
