MnO4¯ + 8 H+ + 5e¯ → Mn+² + 4 H2O (1) In the above reduction half-reaction‚ manganese has undergone a decrease in oxidation number from +7 to +2. In the following oxidation half-reaction‚ each iron atom has undergone an increase in oxidation number from +2 to +3. Fe+²→ Fe+³ + e¯ (2) Oxidation must occur along with reduction. These reactions are called redox (reduction/oxidation ) reactions. The number of electrons lost and gained

Chemistry in Photography Background A photograph is an image made by a photo-chemical reaction which records the impression of light on a surface coated with silver atoms. The reaction is possible due to the light-sensitive properties of silver halide crystals. Equation form for silver halides: Ag + + e - Ag Species produced include: Ag2+‚ Ag2o‚ Ag3+‚ Ag3o‚ Ag4+‚ Ag4o In 1556‚ the alchemist Fabricius was the first to discover that light can photochemically react with these crystals to

Chemistry Coursework – Titration Background Science A titration is the neutralisation of an acid or an alkali. To achieve this‚ one must be added to the other in a specific amount‚ strength and concentration. A substance is neutral when its pH is 7. It is most acidic closer to 0 and is most alkaline closer to 14. 28492453194050 0 7 14 595423979670

cannot carry out photosynthesis‚ so they eat the plants to obtain food‚ hence‚ energy. For that reason the energy for life comes from the sun. 2. Explain what is meant by thermal pollution and discuss the implications for aquatic life. (3 marks) Thermal pollution is a discharge into a river or lake of a lot of hot water which is enough to significantly (2°C to 5°C) increase the temperature of water. This abnormal increase in temperature is potentially harmful to aquatic organisms in these ways:
