Question:
Describe how you would prepare 2.00 L of each of the following solutions:
a. 0.274 M NaOH from 1.00 M NaOH stock solution
- Add _____ mL of 1.00 M NaOH stock solution to a 2.00 L volumetric flask; fill to the mark with water, mixing several times along the way.
b. 0.120 M {eq}\rm K_2CrO_4 {/eq} from 1.75 M {eq}\rm K_2CrO_4 {/eq} stock solution
- Add _____ mL of _____ M {eq}\rm K_2CrO_4 {/eq} stock solution to a 2.00 L volumetric flask; fill to the mark with water, mixing several times along the way.
Defining Stock and Dilute Solutions:
A stock solution has a high concentration of a particular solute and is used for obtaining moderate quantities of solute using small volumes. A dilute solution is one with a low concentration of a particular solute and is used for dealing with substances by using normal volume instead of small volumes. Dilute solutions are useful when dealing with powerful and dangerous substances, such as strong acids and bases.
