  2. Amalgam (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Amalgam_(chemistry)

    For the alkali metals, amalgamation is exothermic, and distinct chemical forms can be identified, such as KHg and KHg 2. [4] KHg is a gold-coloured compound with a melting point of 178 °C, and KHg 2 a silver-coloured compound with a melting point of 278 °C. These amalgams are very sensitive to air and water, but can be worked with under dry ...

    A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.

  5. Sodium amalgam - Wikipedia

    en.wikipedia.org/wiki/Sodium_amalgam

    Synthesis of sodium amalgam. Sodium amalgam, with the common formula Na(Hg), is an alloy of mercury and sodium.The term amalgam is used for alloys, intermetallic compounds, and solutions (both solid solutions and liquid solutions) involving mercury as a major component.

  6. Aluminium amalgam - Wikipedia

    en.wikipedia.org/wiki/Aluminium_amalgam

    This amalgamation can continue well beyond the vulnerable aluminium that was exposed, potentially reacting with a large amount of the raw aluminium before it finally ends. [ 4 ] The net result is similar to the mercury electrodes often used in electrochemistry , however instead of providing electrons from an electrical supply, they are provided ...

  7. PEGylation - Wikipedia

    en.wikipedia.org/wiki/PEGylation

    PEGylation (or pegylation) is the process of both covalent and non-covalent attachment or amalgamation of polyethylene glycol (PEG, in pharmacy called macrogol) polymer chains to molecules and macrostructures, such as a drug, therapeutic protein or vesicle, which is then described as PEGylated.

  9. Gold extraction - Wikipedia

    en.wikipedia.org/wiki/Gold_extraction

    Amalgamation with mercury can be used to recover very small gold particles, and mercury is still widely used in small-scale artisanal mining across the world. [4] Mercury forms a mercury-gold amalgam with smaller gold particles, and then the gold is concentrated by boiling away the mercury from the amalgam.
