Question

Preparation of a Standard Solution by DilutionPurpose: Prepare a standard solution by diluting a stock solution.Lab Procedure: Write a brief procedure on preparing a dilution on a solution.(five steps max)

Answer 1

Step-by-step explanation:

Dilution refers to the process of preparing a lower concentration solution from higher concentrations. Thus, the volume of the solution of interest is combined with the appropriate volume of solvent, reaching the desired concentration.

Therefore, the dilution factor is the total number of volumes your material will be dissolved in.

Dilution solutions are a necessary process in the laboratory, as stock solutions are often purchased and stored in very concentrated forms.

In order for solutions to be used (in a titration, for example), they must be precisely diluted, obtaining a known, lower concentration.

The preparation of solutions from liquid solute should follow the following order:

1. Measure the solute volume;

2. Quantitatively transfer to the volumetric flask;

3. Makeup to volume with solvent;

4. Homogenize the solution;

5. Store the solutions in suitable, labeled containers.
