Introduction: The objective of this experiment is to utilize the techniques of weighing and titrating to determine the total amount of MgSO4 present in an unknown sample. Standardized EDTA will be used to titrate the unknown solution. This type of reaction is a complexation reaction‚ which usually involves Lewis acids and bases. EDTA in complexation reactions serves as a chelating ligand. The base‚ EDTA‚ will bind to the metal ions‚ which serve as the Lewis acid‚ thus playing a role as a ligand

Experiment # 4a Title: Determination of the Hardness of Water from a Waterfall Aim: To determine the molarity of EDTA and to determine the hardness of water by measuring the concentrations of calcium and magnesium in a water sample by titration. Abstract: The aim of this experiment was to determine the molarity of a sample of EDTA and then to use this sample to determine the hardness of a sample of water. This was done using a titrimetric method. This was standardized using calcium chloride.

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

It’s hard to choose a specific leader I admire the most‚ but if I had to choose one‚ it would be Malala Yousafzai. From what I read from her autobiography‚ I greatly admire her acts of leadership‚ courage and determination for change. She may not be as known‚ but her story and her beliefs are just as great as those we look up to today‚ such as Martin Luther King Jr.‚ Gandhi‚ Abraham Lincoln and so on. She is a young Pashtun girl from Pakistan who is suppressed by the Taliban from getting an education

INTRODUCTION: This lab was done to know how diffusion takes place. In the first place‚ particular penetrability is characterize as the particular "determination" with reference to what particles to enter the cell or kept outside of the cell; it is basically specific of what is going in and what is going out‚ primarily supplements going in and squanders going out (Marieb). Moreover‚ specific penetrability happens in two ways: dynamic process that requires ATP for the transportation of cell while

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress
