  2. Base (chemistry) - Wikipedia

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

    Weak bases, such as baking soda or egg white, should be used to neutralize any acid spills. Neutralizing acid spills with strong bases, such as sodium hydroxide or potassium hydroxide , can cause a violent exothermic reaction, and the base itself can cause just as much damage as the original acid spill.

  3. Lewis acids and bases - Wikipedia

    en.wikipedia.org/wiki/Lewis_acids_and_bases

    A Lewis base is often a Brønsted–Lowry base as it can donate a pair of electrons to H +; [11] the proton is a Lewis acid as it can accept a pair of electrons. The conjugate base of a Brønsted–Lowry acid is also a Lewis base as loss of H + from the acid leaves those electrons which were used for the A—H bond as a lone pair on the ...

  4. Alkali - Wikipedia

    en.wikipedia.org/wiki/Alkali

    The terms "base" and "alkali" are often used interchangeably, particularly outside the context of chemistry and chemical engineering. There are various, more specific definitions for the concept of an alkali. Alkalis are usually defined as a subset of the bases. One of two subsets is commonly chosen.

    The smallest base greater than binary such that no three-digit narcissistic number exists. 80: Octogesimal: Used as a sub-base in Supyire. 85: Ascii85 encoding. This is the minimum number of characters needed to encode a 32 bit number into 5 printable characters in a process similar to MIME-64 encoding, since 85 5 is only slightly bigger than 2 ...

  6. Sodium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydroxide

    Sodium hydroxide is a popular strong base used in industry. Sodium hydroxide is used in the manufacture of sodium salts and detergents, pH regulation, and organic synthesis. In bulk, it is most often handled as an aqueous solution, [28] since solutions are cheaper and easier to handle.

  8. Nucleotide base - Wikipedia

    en.wikipedia.org/wiki/Nucleotide_base

    The most common applications are used as fluorescent probes, either directly or indirectly, such as aminoallyl nucleotide, which are used to label cRNA or cDNA in microarrays. Several groups are working on alternative "extra" base pairs to extend the genetic code, such as isoguanine and isocytosine or the fluorescent 2-amino-6-(2-thienyl)purine ...

  9. Organic base - Wikipedia

    en.wikipedia.org/wiki/Organic_base

    Most organic bases are considered to be weak.Many factors can affect the strength of the compounds. One such factor is the inductive effect.A simple explanation of the term would state that electropositive atoms (such as carbon groups) attached in close proximity to the potential proton acceptor have an "electron-releasing" effect, such that the positive charge acquired by the proton acceptor ...
