Even on this basic laboratory experiment requires of those standard obligations,Experiment #3 Preparing and Standardizing a NaOH Solution I. PURPOSE OF THE EXPERIMENT: The purpose of this laboratory activity is to prepare a NaOH solution, determine the concentration of the NaOH solution accurately and precisely, and calculate the % purity of the original solid NaOH. Preparing Stock Solutions. A stock solution is prepared by weighing out an appropriate portion of a pure solid or by measuring out an appropriate volume of a pure liquid, placing it in a suitable flask, and diluting to a known volume. Exactly how one measure's the reagent depends on the desired concentration unit. For example, to prepare a solution with a known molarity you weigh out an ...Title: Preparation of Standard Solutions Objective: 1. To know the preparation techniques of standard base solutions. 2.

Creating Solutions of Standard Molarity. Joshua Farley Partner: Keegan Bradley CHEM 1251L- October 8, 2014 Introduction In this experiment, the main principles of spectrometry were to be studied by creating solutions of a specified molarity and measuring them using the spectrophotometer, or Spec 20, to discover their levels absorbance and transmittance by measuring the amount of light passing ...For example, how would you prepare 500. mL of 0.200 M NaOH(aq) from a stock solution of 1.5 M NaOH? Start by using the dilution equation, M 1 V 1 = M 2 V 2. The initial molarity, M 1, comes from the stock solution and is therefore 1.5 M. The final molarity is the one you want in your final solution, which is 0.200 M. The final volume is the one ...
