Determination of Iron by Reaction with Permanganate-A Redox Titration Purpose: The purpose of this experiment was to find the percentage of iron in an unknown iron oxide sample which could be determined through titration with a standard solution of potassium permanganate. Success in this analysis requires careful preparation and attention to detail. Performing this experiment also provides practice at titrations. The overall reaction is: 8H+(aq) + MnO4-(aq) + 5e- Mn2+(aq) + 4H2O Theory:

Lab 3 : Techniques in Microscopy Title : Preparation of light microscope observe cell organisms. Objective : To observe and investigate the cell structure under the light microscope. Introduction A microscope is an instrument used to magnify and resolve a specimen. It is important to know several important features of microscopy which involves magnification‚ resolution and contrast. Magnification is the enlargement of a specimen while resolution is the ability to distinguish detail or the

(dialysis tubing). The experiment will show how molecules in solution move from areas of higher concentration to areas of lower concentration in the attempt to reach homeostasis in different circumstances. Introduction: The main purpose of this lab was to observe diffusion and osmosis. This is demonstrated using dialysis tubing and a combination of monosaccharaides‚ disaccharides‚ water (H20)‚ and sodium chlorine

Introduction: Recognition of self-determination in international law is new. International law has adopted self-determination as a right in 1941 by UN charter‚ but from the beginning of the civilization the desire for self-determination was there. Debate over this topic is like never ending saga‚ as it’s related to government‚ peace‚ war‚ right

Exercise psychology and Self-Determination Theory Exercise psychology is defined as the study of psychological factors underlying participation and adherence in physical activity programs (Anshel‚ 1948). Health and exercise psychology have gained much prominence over the last few decades especially when it comes to explaining and understanding exercise behaviours (Berger‚ Pargman‚ & Weinberg‚ 2007).The advancement of technology has made life easier resulting in more physically inactivity both

Experiment V02 An analysis of aspirin tablets Procedure a. Weigh accurately a definite number of aspirin tablets (two or three tablets weighing no more than 1.5 g) into a 250 cm3 conical flask. Initiate the hydrolysis of the aspirin by adding 25 cm3 of 1.0 M sodium hydroxide by pipette‚ diluting with approximately the same volume of distilled water. Warm the flask over a tripod and gauze for ten minutes to complete the hydrolysis. b. Cool the reaction mixture and transfer with washings to

Objective To determine soluble solid concentration in some fruits including tropical and temperate fruits by using handheld refractometer. Introduction “Sugar are the major soluble in fruits juices and estimate of sweetness. Other soluble materials include organic and amino acids‚ soluble pectins‚ and others. Soluble solid concentration can be determined in a small sample of fruits juice using a hand held refractometer. The measurement must be made at 20°C to get an accurate value. This instrument

For instance‚ one who comes from hardship certainly can work through and excel in a way some call unbelievable due to grit. A passionate individual who stays committed to a long term goal will not have things handed to them by chance‚ but will work hard to achieve challenging goals. By being steadfast‚ one’s tenacity is admirable especially when becoming triumphant against all odds. As Angela Duckworth‚ professor of psychology‚ states in her best seller Grit‚ “The highly accomplished are gratified
