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

Lime scale form when hot water is heated about 61’C. All the acids listed about remove lime scale because the ions in the acids react with the calcium ions in limescale to then form a soluble salt. The acids also react with the carbonates in lime scale to produce water and carbon dioxide. Then the whole solution washes out taking away as much lime scale and possible. Sulfamic acid The advantages of using sulfamic acid as a de-scaler are that it is the faster de-scaler which means it can give

Non-renewable energies are effecting our environment for the worse. The search for new energy source such as alternative energy sources are starting to become an important factor in the human society. Solar power energy is one alternative energy source often over looked that our society should begin using. Solar power energy works like this‚ “When sunlight hits a solar panel‚ it makes electrons in the silicon move around. (Electrons are teeny tiny specks—they’re way too small for us to see‚ even

Today‚ many countries are depending more and more on nuclear energy to produce electricity. Although‚ nuclear energy can bring many benefits‚ such as nuclear fission‚ which releases no carbon dioxide‚ it also brings many risks to many countries that use nuclear energy. This was proved‚ in many disasters that nuclear energy caused years ago‚ like the Chernobyl Disaster in April 26‚ 1986‚ which was said that‚ “the radiation released was to be 200 times that of Hiroshima and Nagasaki nuclear bombs
