A protocol calls for 1 liter of solution that is 1.5 % (w/v) NaCl, 5mM Tris (pH 8.0), 10% (w/v) Carnation Instant Milk (we really do use this in lab!), and 0.03% (v/v) Tween-20 detergent. How do you make this solution?
Question 4. You are on a field trip with your professor and he asks you to make a fixative solution to collect and preserve specimen. You are told to prepare 200 mL of fixative solution containing 30% formaldehyde (vol/vol), 1X glycerol and 2.5 mM sodium chloride (NaCI). In the field trip van you find a stock of 100% pure formaldehyde (liquid), a 10X glycerol stock (liquid), plenty of water and a stock solution of 5M NaCl. There are also all kinds of pipets, cylinders and beakers to measure volumes. 1. a) provide calculations and describe the process of making the fixative solution?
Question 5 In Step 8 (see below, as well as in the presentation), three different slimes were prepared by adding different amounts of borax solution. Which of the following statements is/are correct? Step 8: Prepare the following slimes and evaluate their properties Sample 1 3 PVA solution 40 mL 40 mL 40 mL Borax solution 10 mL 5 mL 1 mL Deionized water O mL 5 mL 9 mL Breaking length Bounce height 30cm 70cm NA 5cm 10cm NA O The more borax we add, the more rigid the slime will become. O The less borax we add, the less elastic the slime will become. O The change in its properties is due to the added amount of water which will affect the structure of the slime. O The water is added in order to have the same final volume of reactants.
