What is the aim of Borax experiment

Question

Procedure: Weigh out 1.907 g Borax on sensitive Place the Borax in a 100 mL beaker.  Add a small volume of distilled, deionized water to dissolve the borax (if it is not dissolved stir it with stirrer).  Then pour the solution in to a volumetric flask and fill the flask by D.W to the 100 mL line.

 I just want to know what is the aim of this experiment and what could be the discussion about it?

formula of Borax (Na2B4O7•10H2O)

thank you.

Answer 1

1. How do you prepare a solution of Borax with certain molarity?
2. What is the molarity of the solution?
3. They want the students to understand in order to make a solution of a volume of 100 mL, you should not dissolve the required amount in 100 mL of water.
4. Aim: To understand the proper technique for making a standard solution.
