Prior to begin the experiment‚ preparation for some solutions is required to enhance the lab performance. The solutions needed are standardized potassium bromate‚ standardized sodium thiosulfate‚ and starch indicator. First‚ to prepare a starch indicator‚ pulverize 1g of soluble starch and add 15mL of water to make it as a paste-like substance. Dilute it with about 500mL of boiling water‚ and continue to heat until the mixture becomes clear. Cool it to room temperature and save it into a stoppered

The experimental samples for the pH concentration experiment were put together by using a 10ml-graduated cylinder to obtain 4ml of each pH buffer to insert into cuvettes‚ a micropipette was then used to obtain 0.5ml of catechol and 0.5ml of the catechol oxidase. The pH buffer was made first to avoid any denaturation of the catechol oxidase. Our positive control for this experiment was pH 7 because that is the pH level of most cell membranes in the cytoplasm (Whitson‚ 2016.) Our negative controls

1. Take 5 tea bags and record the weight on the 3decimal place balance. 2. Take a 500 ml beaker add 200 ml of 20°C distilled water to it. Now place 5 tea bags in this beaker. 3. Boil the content in a beaker‚ in a 40°C hot water bath for 5 minutes. 4. Pour the mixture into a new beaker. 5. Gently squeeze the tea bags (you can use a teaspoon to help when using high temperature of water) to make sure that all the water is in the beaker. 6. Cool the aqueous solution in an ice bath‚ use a thermometer

A Medical Laboratory Technician run test on blood and body fluids to help give doctors answers; answers that can help doctors diagnose what’s wrong with the patient before starting a treatment plan. Throughout these past four years‚ I’ve learned a lot‚ high school has taught me a variety of things‚ but it most importantly has taught me the different type of careers there are. Before I entered high school‚ I didn’t know what a Medical Laboratory Technician was‚ I didn’t even know that was a career;

Student number: 658184 Due Date: 19th Sept 2012 Paracetamol: Preparation‚ Purification and Analysis 1.1 Introduction Paracetamol (N- (4- hydroxyphenyl) ethanamide) or acetaminophen is a widely used analgesic (pain reliever) and antipyretic (fever reducer). It is a relatively safe drug though toxicity has been observed with very high doses.1 according to the British Pharmacopeia (BP) 111 paracetamol should contain between 95.0%- 105.0% of the stated product.2 It can be synthesised by reacting 4-aminophenol

INTRODUCTION The main theory behind this experiment is that by setting up several apparatuses using varying amount of t-butyl alcohol‚ distilled water‚ or an unknown liquid‚ the freezing point of t-butyl alcohol‚ the molal freezing point and the molar mass of an unknown can be determined. The equations pertinent to this experiment include the following: mc= ∆Tf=Tf-Tf’=(Kf)(mc) mc= mc= mc= gram molar mass of solute‚ g mole^-1= kf=∆Tf/ mc mass of unknown ‚g=(volume of
