POT TENDING MACHINE PTM is the crucial equipment of large anode pre-baking workshop. It is used in the environment of high temperature‚ large current‚ strong magnetic field and HF gas. It can perform the following procedures ANODE CHANGE: Anode in the pots is changed at an interval of every 27 days since daily 1.5 cm of the anode gets consumed. A carbon block is usually 55 cm high of which only 40 cm can be used up. The main reason behind the anode consumption is the following electrolytic

A potato battery is a type of electrochemical cell. An electrochemical cell converts chemical energy into electrical energy. In the potato battery‚ there is a transfer of electrons between the zinc coating the galvanized nail that will be inserted into the potato and the copper wire that will be inserted another part of the potato. The potato conducts electricity‚ yet keeps the zinc ions and copper ions separate‚ so that the electrons in the copper wire are forced to move (generate current). It’s

The synthesized product‚ SnI4 was found to have a yield of 0.0227 g which corresponded to a 4.63 % yield. The synthesizing process of SnI4 showed distinctive changes. After the addition of dichloromethane the solution turned to a purple color‚ this then turned into a purple-burgundy colour after gravity filtration; the desired colour was observed only when vacuum filtration was applied. The purple solution turned into damp orange crystals and after thorough drying the crystals were a bright‚ dry

1 PRACTICE EXAM (not all questions pertain to a specific mid-term). This is taken from an earlier final exam. 1. (4 pts) Permanganate ion oxidizes sulfide ion to elemental sulfur (which you should represent as a single S atom) and is reduced to MnO2 in basic solution. In the balanced equation for this reaction‚ which you should determine in the work area‚ how many water molecules and hydroxide ions are needed in the final balanced equation?

Most of the metals are solids; few of them are liquids‚ such as mercury and cesium. Density of metals is not similar also. For example‚ sodium has density of 0.97g/cm3 while lead has density of 11.4g/cm3. Melting point of sodium is 98.0oC while for lead it is 327.6oC. Metals have the capability

Indonesia national. I graduated in July 2012‚ from Bandung Institute of Technology‚ Indonesia and hold a Bachelor degree in Chemistry. I choosed to focus on applied electrochemistry because i have many curiosities to study this field. While studying electrochemistry‚ i fell very interisting to observe theory and application about electrochemistry. During my bachelor study‚ i have been proving myself to retain the top position of student in the class so that i have successfully achieved the scholarship (2009-2012)

our lives and to this day Electrochemistry is a standard course of study. While listening to lessons on Electrochemistry‚ many students may wonder why it was ever invented‚ if it was really ever necessary to invent it and if the world would be better off without it. With the small experiments that follow‚ we hope to make peace between these students and the study of Electrochemistry. These fun and simple experiments can teach the fundamental concepts of Electrochemistry without asking much of the

Batteries contain heavy metal such as mercury‚ cadmium and nickel which can contaminate the environment when batteries are improperly disposed of. When flamed‚ certain metals might be release to the air or be left in the ash of the burnt battery. By draining and neutralising acid from the batteries and recycling them our problem is solved. The one world factors I shall be looking at this from is environment and economic. By: www.leadbatteryuniversity.uk Batteries must always be drained before

What is Chemistry? Chemistry is the study of matter and energy and the interactions between them. This is also the definition for physics‚ by the way. Chemistry and physics are specializations of physical science. Chemistry tends to focus on the properties of substances and the interactions between different types of matter‚ particularly reactions that involve electrons. Physics tends to focus more on the nuclear part of the atom‚ as well as the subatomic realm. Really‚ they are two sides of the
