Question 1:

Which technique is commonly used for the quantitative analysis of the concentration of a solute in a solution?

Explanation: Titration is commonly used for the quantitative analysis of the concentration of a solute in a solution. It involves the controlled addition of a solution of known concentration (titrant) to react with the analyte until the reaction is complete, allowing the determination of the analyte's concentration.

Question 2:

What is the purpose of a calibration curve in quantitative analysis?

Explanation: The purpose of a calibration curve in quantitative analysis is to establish a relationship between the concentration of a solute and a measurable property, such as absorbance or volume. This allows the determination of the unknown concentration of the solute based on its measured property.

Question 3:

What is the term used to describe the lowest concentration of an analyte that can be reliably detected and quantified in an analytical method?

Explanation: The term used to describe the lowest concentration of an analyte that can be reliably detected and quantified in an analytical method is the limit of detection. It represents the minimum amount of analyte that can be distinguished from background noise.

Question 4:

What is the standard solution in a titration method?

Explanation: In a titration method, the standard solution refers to the solution of known concentration (titrant). It is carefully prepared and used to react with the analyte until the reaction is complete, allowing the determination of the analyte's concentration.

Question 5:

Which term is used to describe the ratio of the moles of solute to the volume of the solution?

Explanation: The term used to describe the ratio of the moles of solute to the volume of the solution is molarity. It is expressed in moles per liter (mol/L) and is commonly used to represent the concentration of a solute in a solution.
