Question

Describe how to prepare the solution using a 250.0 mL volumetric flask by placing the steps in the correct order. Not all of the steps will be used.

a. Transfer the measured amount of NaCl to the volumetric flask.
b. Dilute the solution with water to the 250.0 mL mark.
c. Add more water to the flask, but still under a total volume of 250.0 mL, and mix.
d. Hold the cap firmly in place and invert the flask many times.
e. Dissolve the NaCl in less than 250 mL of water and mix well.
f. Dissolve the measured amount of NaCl in 250 mL of water.

Answer 1

Answer:

The correct order will be

a. Transfer the measured amount of NaCl to the volumetric flask.

e. Dissolve the NaCl in less than 250 mL of water and mix well.

b. Dilute the solution with water to the 250.0 mL mark.

Explanation:

Preparation of NaCl solution in 250.0 ml volumetric flask:

Add the weighed NaCl directly to volumetric flask and add small amount of water to it and mix it will until all NaCl gets dissolved( if not add small water amount of water more)

After dissolving NaCl add the water upto the mark.

The correct order will be

a. Transfer the measured amount of NaCl to the volumetric flask.

e. Dissolve the NaCl in less than 250 mL of water and mix well.

b. Dilute the solution with water to the 250.0 mL mark.
