    en.wikipedia.org/wiki/List_of_computer-assisted...

    Computer-assisted organic synthesis software is a type of application software used in organic chemistry in tandem with computational chemistry to help facilitate the tasks of designing, predicting, and producing chemical reactions. CAOS aims to identify a series of chemical reactions which, from a starting compound, can produce a desired molecule.

  3. Molecular design software - Wikipedia

    en.wikipedia.org/wiki/Molecular_design_software

    Molecular design software is notable software for molecular modeling, that provides special support for developing molecular models de novo.. In contrast to the usual molecular modeling programs, such as for molecular dynamics and quantum chemistry, such software directly supports the aspects related to constructing molecular models, including:

  4. Salting out - Wikipedia

    en.wikipedia.org/wiki/Salting_out

    Salting out (also known as salt-induced precipitation, salt fractionation, anti-solvent crystallization, precipitation crystallization, or drowning out) [1] is a purification technique that utilizes the reduced solubility of certain molecules in a solution of very high ionic strength.

  5. Salt metathesis reaction - Wikipedia

    en.wikipedia.org/wiki/Salt_metathesis_reaction

    This reaction usually produces a salt. One example, hydrochloric acid reacts with disodium iron tetracarbonyl to produce the iron dihydride: 2 HCl + Na 2 Fe(CO) 4 → 2 NaCl + H 2 Fe(CO) 4. Reaction between an acid and a carbonate or bicarbonate salt yields carbonic acid, which spontaneously decomposes into carbon dioxide and water. The release ...

  6. Building block (chemistry) - Wikipedia

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

    Building block is a term in chemistry which is used to describe a virtual molecular fragment or a real chemical compound the molecules of which possess reactive functional groups. [1] Building blocks are used for bottom-up modular assembly of molecular architectures: nano-particles , [ 2 ] [ 3 ] metal-organic frameworks , [ 4 ] organic ...

  7. Salt (chemistry) - Wikipedia

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

    The component ions in a salt can be either inorganic, such as chloride (Cl −), or organic, such as acetate (CH 3 COO −). Each ion can be either monatomic (termed simple ion), such as sodium (Na +) and chloride (Cl −) in sodium chloride, or polyatomic, such as ammonium (NH + 4) and carbonate (CO 2− 3) ions in ammonium carbonate.

  8. Magnus's green salt - Wikipedia

    en.wikipedia.org/wiki/Magnus's_green_salt

    Magnus's green salt has the same empirical formula as cis-PtCl 2 (NH 3) 2 ("Peyrone chloride") and trans-PtCl 2 (NH 3) 2. [4] These cis and trans compounds are molecules, whereas Magnus's green salt is a polymer. This difference is manifested by the solubility of the molecular complexes in water, whereas Magnus's green salt is insoluble.

  9. Acid salt - Wikipedia

    en.wikipedia.org/wiki/Acid_salt

    A salt containing reactive cations undergo hydrolysis by which they react with water molecules, causing deprotonation of the conjugate acids. For example, the acid salt ammonium chloride is the main species formed upon the half neutralization of ammonia in aqueous solution of hydrogen chloride: [2] NH 3 + HCl(aq) → [NH 4] + Cl − (aq)
