laboratory assignment 3 was to measure the rate at which a chemical reaction takes place. For the purpose of this lab we measured the rate a balanced oxidation/reduction reaction between iodine‚ hydrogen‚ and bromate ion occurs. The above reaction occurs slowly so we used a coupled iodine clock reaction to measure the rate of the oxidation/reduction reaction because it occurs much faster but is still dependent upon the other reaction. To accomplish this‚ two mixtures were prepared in separate Erlenmeyer

The total protein content was estimated as proposed by Lowry et al. A bovine serum albumin stock solution (1mg/ml) was prepared in sodium hydroxide (1N). Five different concentrations (0.2‚ 0.4‚ 0.6‚ 0.8‚ 1 ml) of the prepared solution were taken in different test tubes. In another set of test tubes‚ 0.1 and 0.2 ml of the extract were taken. In each test tube‚ the volume was made up to 1 ml‚ followed by addition of the prepared alkaline solution (5 ml) at room temperature. The solutions were left

Concentration vs Rate of reaction Brandon Introduction A reaction rate is the speed at which a chemical reaction will occur. Heat‚ concentration of a chemical‚ Surface area or a catalyst‚ will affect the rate of reaction. The concentration of a chemical will speed up of the reaction because the reactant particles have become more crowded therefore increasing the chance of productive collisions. In this practical the chemicals will be Sodium thiosulphate and Hydrochloric acid which will produce

By definition‚ product placement is the purposeful incorporation of a brand into an entertainment vehicle. (Reichert‚ 2008) The textbook calls this strategic placement of products in TV shows‚ movies‚ and other entertainment vehicles‚ a hybrid of traditional advertising. This suggests that not only is the product being promoted‚ but it is done in such a way that the audience may not even realize they are being sold to. It has been said to “epitomize the blurring of the lines between advertising

11.2013 – my first day of placement My first day of placement was something of a disaster; nothing went right on the first day and it made me go into a negative state of mind which meant that everything that day didn’t go right and I didn’t feel that I enjoyed it. First of all I was an hour late for placement as I was unable to find it; this made me feel negative about the placement and meant that I was not going to enjoy the placement. Once I had arrived at placement‚ the staff didn’t even know
