Objective: Probably the most practical of the tasks, this task shows you how to write recipes for common biochemistry lab solutions, using both solid solutes and concentrated solutions. From Chapter 13: To make an aqueous solution from a solid solute: "For a Molute) to a sufficient quantity of distilled water. :ix thoroughly, and then make up the volume of the solution to thoroughly again." liters (or milliliters) with distilled water and mix 1. Ringer's solution is a commonly-used medical solution that is isotonic with mammalian body fluids. It has the following four components (according to Cold Spring Harbor Labs protocols): 0.125M sodium chloride 1.50mM calcium chloride dihydrate (mM= "millimolar"; CaCl2H2O) 5.00mM potassium chloride 0.800mM sodium phosphate, dibasic (Na2HPO4) Write a recipe, using the recipe template above, to make 1.00L of Ringer's solution from the solid solutes. Note that the salts will not react with each other in the solution. Show your calculation setups below. To dilute a stock solution to a lower concentration: "For a M solution of (name of solute) : To liters (or milliliters) of distilled water, add liters (or milliliters) of M stock solution of (name of solute) and mix thoroughly." 2. Acids and bases are common laboratory reagents, but are rarely used at the concentrations that they are shipped in; acid and base manufacturers expect that their clients will dilute the concentrated acids and bases for their own needs. According to LabChem. Inc., glacial acetic acid (the most concentrated form) is 17.4M. We will be using 6.00M acetic acid in a future lab, and will need 250.mL for the whole class. Write a recipe, using the recipe template above, to make 250 . mL of 6.00M acetic acid from glacial acetic acid. Show your calculation setup below
