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

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

Wage determination in perfect and imperfect markets Perfect competition In perfect labor markets‚ everyone is wage taker – both the employee and the employer. On the one hand‚ the employer and his firm cannot control the market as there are too numerous firms and the firm is price taker on the product market and labor market. On the other hand‚ the workers cannot control their wage as they have no economic power to do so or they are of a clearly definite type. In perfect competition there

DETERMINATION OF BOILING POINTS Introduction: The boiling point of a compound is the temperature at which it changes from a liquid to a gas. This is a physical property often used to identify substances or to check the purity of the compound. It is difficult‚ though‚ to find a boiling point. Usually‚ chemists can only obtain a boiling range of a 2 - 3oC accuracy. This is usually sufficient for most uses of the boiling point. Purpose: The purpose of this experiment is to determine the

ESSAY: Describe a goal or challenge in your past that required perseverance and determination to accomplish. When I was a young child I set a goal to serve a full-time mission for the Church of Jesus Christ of Latter Day Saints. During my teenage years I experienced many obstacles and challenges that seemed to detour me from achieving my goal. I participated in many extracurricular events that ranged from high school baseball to scouting. I tasted failure and success any many of these endeavors

UNKNOWN SAMPLE #97 COMPLEXOMETRIC DETERMINATION OF WATER HARDNESS DR. BUDRUK CHM 152 LL SEAN MARKIS 4 FEBRUARY 2015 Introduction Using a Lewis base neutral molecule to donate electron pairs (ligands) to a Lewis acid metal ion center to form a single cluster (complex) ion. When the complex ions forms with a metal ion (chelation) the ligand used is called the (chelating agent). EDTA acts as a great chelating agent due to the Nitrogen and Oxygen donating an electron pair to the

Self-Determination “I have not failed. I’ve just found 10‚000 ways that won’t work.” ― Thomas A. Edison I believe that if you have self-determination then there is no such thing as failure‚ only improvements. This means that if I work hard enough and put my mind to it‚ I can do it. I may not reach my accomplishments right away but if I do want to be successful I will have to have failed many times before I reach what I to accomplish. Possibilities are endless with self-determination. I
