Log Dilutions

What is a log dilution?

• A log dilution is a method used in science to reduce the concentration of a substance by a logarithmic scale.

• A log dilution is a method used in science to separate the components of a substance by a logarithmic scale.

• A log dilution is a method used in science to measure the volume of a substance by a logarithmic scale.

• A log dilution is a method used in science to increase the concentration of a substance by a logarithmic scale.

How is a log dilution calculated?

• By dividing the dilution factor by the logarithm.

• By taking the logarithm of the dilution factor.

• By multiplying the dilution factor by the logarithm.

• By adding the dilution factor to the logarithm.

If a solution is diluted by a factor of 10, how many log dilutions have occurred?

• 1

• 0

• 5

• 10

What does a log dilution factor of 2 mean?

• Concentration is reduced by a factor of 2 for each dilution step.

• Concentration is reduced by a factor of 2 for each dilution step.

• Concentration is doubled for each dilution step.

• Concentration is reduced by a factor of 2 for every two dilution steps.

If a solution has a log dilution factor of 3, what is the dilution ratio?

• 1/4

• 1/3

What does it mean if a log dilution result is negative?

If a solution is diluted by a factor of 1000, how many log dilutions have occurred?

• 2

• 1

• 3

How do you interpret a log dilution result of 0?

• The concentration is reduced by 0%

• The original concentration remains unchanged.

• The concentration is diluted by 100%

• The concentration is multiplied by 0

What is the purpose of performing log dilutions in scientific experiments?

• To dilute the concentration of the sample.

• To create a range of concentrations for testing and analysis.

• To increase the accuracy of the experiment.

• To save time and resources.
