CAUTION: It is important to always use care when handling reagents. For example, iodine will stain clothes and skin so wear gloves, goggles, and a lab coat when using this reagent.
To prepare a 1 M glucose solution, begin by using a stir bar to dissolve 180.2 g of glucose in 500 mL of distilled water, increasing the volume to 1 L once the solute has dissolved in the smaller volume of solvent.
To prepare a 10% cornstarch solution, first use a hotplate to boil 1 L of distilled water.
Then make a paste with 8 g of cornstarch and 10 mL of cold water.
Now, dissolve the cornstarch paste into the boiling water.
To prepare a 10% gelatin solution, combine 1 g of gelatin powder with 1 L of distilled water.
Then, use the hotplate to boil the solution until the gelatin has fully dissolved, taking care not to burn it.
