1. You will make two solutions with a concentration of about I M (Procedure Part Bi ane B2). Why is it acceptable to make these in beakers rather than a volumetric flasks? 2. Identify each of the following household substances as a strong electrolyte, weak electrolyte, or non-electrolyte: salt solution (in water), sugar solution (in water), bieaci, vinegar, and baking soda solution (in water). Give reasoning for your assignment. a. Hypothesize what will happen to the color of the gold nanoparticle suspension when each of the solutions is added (separately). 3. In addition to the 13 nm nanoparticles you will make in this experiment, find another size of a gold nanoparticle (make sure to cite your sources). a. In an aqueous solution, which is larger, the gold nanoparticle or a water molecule? b. What is your reasoning for this answer? c. By how much? d. Make an analogy of this size difference using a human. e. If you could see the entire gold nanoparticle, would you also be able to see a water molecule next to the particle? 4. Identify any potentially hazardous steps in your procedure. In your own words, explain what safety procedures should be followed and why. 1.

1 These solutions can be prepared in beaker because we need approximate molarity of the solution so the slight difference will not matter So this is acceptable to use beaker High curvature of the meni... View the full answer
