Multiple Choice
Why is a serial dilution often performed in laboratory settings?
A
To increase the concentration of a solution gradually.
B
To directly measure the pH of a solution.
C
To separate components of a mixture based on solubility.
D
To achieve a precise concentration of a solution by stepwise dilution.
Verified step by step guidance
1
Understand the purpose of a serial dilution: It is a method used to create a series of solutions with decreasing concentrations by diluting a stock solution stepwise.
Recognize that serial dilutions are not used to increase concentration, but rather to decrease it in a controlled manner.
Note that serial dilutions are not directly used to measure pH, although they can prepare solutions for pH measurement.
Understand that serial dilutions are not used to separate components based on solubility; this is typically done using techniques like filtration or chromatography.
Conclude that the primary reason for performing a serial dilution is to achieve a precise concentration of a solution by stepwise dilution, allowing for accurate experimental conditions.
