Interpretation Introduction

Interpretation:

The reason for the seal to be broken in vacuum filtration before the flow of water to water aspirator is turned off should be determined.

Concept introduction:

Filtration is one of the purification methods used for purification of an organic liquid to make them free from solid impurities. The two kinds of filtration techniques used in organic chemistry are as follows:

  • Gravity filtration.
  • Vacuum filtration.

Vacuum filtration is a technique of filtration used to separate solid product from liquid when the required compound is solid. Vacuum filtration is considered a fast and efficient method to filter. A Buchner's funnel or Hirsch funnel are utilized to create vacuum to suck the fluid through the filter in the vacuum filtration.

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.…
