Experiment 1 : Redox Titration Using Sodium Thiosulphate Abstract This experiment is to determine the concentration of oxidizing solution using the iodine/ thiosulphate titration where the reducing solution is potassium iodate solution and the oxidizing solution is sodium thiosulphate solution. Potassium iodate solution which is an oxidizing agent is added into an excess solution of acidified potassium iodide. This reaction will release iodine. Potassium iodide is acidified with sulphuric acid

Amoxicillin Amoxicillin is a penicillin antibiotic. It fights bacteria in your body. Amoxicillin is used to treat many different types of infections caused by bacteria‚ such as ear infections‚ bladder infections‚ pneumonia‚ gonorrhea‚ and E. coli or salmonella infection. Amoxicillin is also sometimes used together with another antibiotic called clarithromycin (Biaxin) to treat stomach ulcers caused by Helicobacter pylori infection. This combination is sometimes used with a stomach acid reducer

Role of Laboratory in Clinical Trials Laboratory data forms the backbone of all the clinical trials. Hence it is important to have good laboratory support and interaction with the laboratory in all the clinical trials. Clinical trials typically include two kinds of activity a) evaluation and validation of new clinical laboratory testing systems or b) laboratory evaluation of patients subjected to new clinical products or protocols‚ particularly those related to new drug development
