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

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.…
