PPT-Assay of NaOH Solution

Lecturer Luma Amer Department of Pharmaceutical Chemistry Collage of pharmacy 1 st stage 2st lab Lab 2 Assay of NaOH Solution NaOH secondary standard solution because it is a hygroscopic so in BP . From Solids. What are molar solutions?. A molar solution is one that expresses “concentration” in moles per volume. Usually the units are in mol/L. mol/L can be abbreviated as M or [ ]. Molar solutions are prepared using:. Reading from the text. Procedure #1: titration. First, set up the clean, dry burette with a funnel on the top of it. Make sure that the burette is closed. Then, add the . NaOH. solution to the burette. Immediately clean up any spills of . 6.03 Honors. 6.03 Calorimetry honors. In this experiment, you will determine the quantity of heat involved in two different chemical processes. The heat given off or absorbed will be measured using an insulated calorimeter. Be sure to record all measurements carefully, as you will use the data to calculate the enthalpy change of each process.. Clicker . Questions. Lynn . Mandeltort. Auburn University. Chapter 4. .
