Preparing a Solution by Dilution
When a solution of a desired concentration needs to be prepared, it can be done by diluting a stock solution. This is accomplished by adding a solvent, such as water, to the stock solution to decrease its concentration.
Steps for preparing a solution by dilution:
1. Determine the desired concentration: The concentration of the solution to be prepared is determined beforehand.
2. Calculate the volume needed: The volume needed can be calculated using the following formula:
V1C1 = V2C2
Where V1 is the volume of the stock solution, C1 is the concentration of the stock solution, V2 is the volume of the final solution, and C2 is the desired concentration of the final solution.
3. Measure out the stock solution: The measured amount of stock solution is transferred to a clean beaker or flask.
4. Add the solvent: The solvent, usually water, is added to the stock solution.
5. Mix the solution: The solution is mixed thoroughly to ensure that the concentration is uniform.
6. Check the concentration: The concentration of the resulting solution can be checked using a spectrophotometer or other analytical methods.
Therefore, option D is the correct answer as a stock solution is used to prepare a solution of a desired concentration by dilution.

Both A and D are correct but option D is best as stock solution have only one reason and that is to store it in less space and make dilluted solution from it easily.
