Preparation of dilutes solution of acetic acid
Accepted Answer
To prepare a dilute solution of acetic acid (CH3COOH), you'll need to dilute a concentrated solution with water. Here's a general procedure:
1. Calculate the volume of concentrated acid needed: Use the formula M1V1 = M2V2, where:
M1 = Molarity of concentrated acetic acid (usually 17 M)
V1 = Volume of concentrated acetic acid (what you need to calculate)
M2 = Desired molarity of the dilute solution
V2 = Desired volume of the dilute solution
2. Measure the calculated volume of concentrated acetic acid: Use a graduated cylinder or pipette to accurately measure the required volume.
3. Add the concentrated acid to a volumetric flask: Slowly pour the acid into a volumetric flask containing a small amount of distilled water. Always add acid to water, not water to acid, to prevent splashing and heat generation.
4. Add distilled water to reach the desired volume: Fill the volumetric flask with distilled water until the meniscus reaches the calibration mark. Mix the solution thoroughly.
5. Label the solution: Properly label the container with the concentration, date, and any other relevant information.
