pre - lab 7 question 1 4.75 points
a student uses a 1.00 m stock solution of a reagent to prepare a 0.250 m dilution in one dilution step. what type of dilution would this be classified as?
a serial dilution
b simple dilution
c dilutions cannot be classified into types

Explanation:

• Simple dilution: Involves diluting a stock solution in one step. Here, the student is going from a \(1.00\ M\) stock to \(0.250\ M\) in one dilution step.
• Serial dilution: Requires multiple dilution steps (e.g., first diluting from stock to an intermediate concentration and then further diluting that intermediate to get the final concentration). Since it is done in one step, it is not a serial dilution.
• Dilutions can be classified: There are well - defined types like simple and serial dilutions.

Answer:

B. simple dilution
