Whether solution made by addition of 40 g Li 2 SO 4 to 75.0 g of water at 40 ° C is saturated or unsaturated has to be determined. Also, mass percent of Li 2 SO 4 has to be determined. Concept Introduction: Solution is used for description of any system that consists of mixture of substances dissolved in another substance. It has two components, solute and solvent. Component present in less quantity and is dissolved in another component is called solute while the one that dissolves solute in it and is present in more amounts is called solvent. Types of solutions: 1. Saturated solution When maximum amount of solute is dissolved in solvent, solution becomes saturated. Additional solute remains undissolved in such types of solutions. 2. Unsaturated solution When solute less than maximum capacity is added to solvent, unsaturated solution is formed. Additional solute gets dissolved in such solution. 3. Supersaturated solution. Such types of solutions consist of extra solute than that can be actually dissolved in solvent.

Concept Introduction:

Solution is used for description of any system that consists of mixture of substances dissolved in another substance. It has two components, solute and solvent. Component present in less quantity and is dissolved in another component is called solute while the one that dissolves solute in it and is present in more amounts is called solvent.

Types of solutions:

1. Saturated solution

When maximum amount of solute is dissolved in solvent, solution becomes saturated. Additional solute remains undissolved in such types of solutions.

2. Unsaturated solution

When solute less than maximum capacity is added to solvent, unsaturated solution is formed. Additional solute gets dissolved in such solution.

3. Supersaturated solution.

Such types of solutions consist of extra solute than that can be actually dissolved in solvent.

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.…
