metal in contact with molten salts‚ metals can be extracted from one phase to the other. This is related to a mercury electrode where a metal can be reduced‚ the metal will often then dissolve in the mercury to form an amalgam that modifies its electrochemistry greatly. For example‚ it is possible for sodium cations to be reduced at a mercury cathode to form sodium amalgam‚ while at an inert electrode (such as platinum) the sodium cations are not reduced. Instead‚ water is reduced to hydrogen. A detergent or

The ether‚ also known as aether‚ was believed to occupy all of space with a material that was considered to be a mechanically structured substance. It would be composed of particles that move in particular ways so as to produce the forces found in the phenomena of electricity and magnetism. This was on the basis of the work achieved by James Clerk Maxwell‚ who in the first developed the theory that predicted the existence and the means of producing radio waves in the 1850s. Before Albert Einstein’s

Chemical Reactions- Sodium Hydroxide A chemical reaction is a change where two or more substances are changed into a new substance. You can identify a chemical reaction by colour change‚ effervescence (bubbles)‚ when light or heat given off‚ and the change is usually irreversible. There are 6 main types of chemical reactions- combustion (often called burning)‚ synthesis‚ decomposition‚ neutralization‚ single replacement and double replacement. A combustion reaction is a reaction with oxygen‚ and
