Question 3. Your professor asks you to make a staining solution to stain and observe specimens under the microscope. You are told to prepare 100 mL of staining solution containing 40% methanol, 1X hematoxylin dye and 0.01 M calcium chloride (CaC12). In the histology lab, you find a stock of 100% pure methanol (liquid), a 10x hematoxylin dye stock solution (liquid), plenty of water and a stock solution of 5M CaC12. There are also all kinds of pipets, cylinders and beakers to measure volumes. a) Describe how you make the staining solution? b) On your following trip to the histology lab, you realize that all the pipets to accurately measure volumes smaller than 1 ml are broken. What alternative method do you need to use to avoid pipetting small volumes (just explain in a couple of sentences, no calculation needed)?
