  2. Chemical reaction - Wikipedia

    en.wikipedia.org/wiki/Chemical_reaction

    The equilibrium is determined by the acid and base dissociation constants (K a and K b) of the involved substances. A special case of the acid-base reaction is the neutralization where an acid and a base, taken at the exact same amounts, form a neutral salt. Acid-base reactions can have different definitions depending on the acid-base concept ...

  3. Single displacement reaction - Wikipedia

    en.wikipedia.org/wiki/Single_displacement_reaction

    Metals react with acids to form salts and hydrogen gas. Liberation of hydrogen gas when zinc reacts with hydrochloric acid. + () + [2] [3] However less reactive metals can not displace the hydrogen from acids. [3] (They may react with oxidizing acids though.)

  4. Chemical synthesis - Wikipedia

    en.wikipedia.org/wiki/Chemical_synthesis

    Medicine: Organic synthesis plays a vital role in drug discovery, allowing chemists to develop and optimize new drugs by modifying organic molecules. [9] Additionally, the synthesis of metal complexes for medical imaging and cancer treatments is a key application of chemical synthesis, enabling advanced diagnostic and therapeutic techniques. [10]

    en.wikipedia.org/wiki/Outline_of_chemistry

    The following outline acts as an overview of and topical guide to chemistry: . Chemistry is the science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties, structure, composition, behavior, and changes as they relate to the chemical reactions.

  6. Koch reaction - Wikipedia

    en.wikipedia.org/wiki/Koch_reaction

    The Koch reaction is an organic reaction for the synthesis of tertiary carboxylic acids from alcohols or alkenes and carbon monoxide.Some commonly industrially produced Koch acids include pivalic acid, 2,2-dimethylbutyric acid and 2,2-dimethylpentanoic acid. [1]

  7. Acid–base reaction - Wikipedia

    en.wikipedia.org/wiki/Acid–base_reaction

    In chemistry, an acid–base reaction is a chemical reaction that occurs between an acid and a base.It can be used to determine pH via titration.Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acid–base theories, for example, Brønsted–Lowry acid–base theory.

  8. Acid catalysis - Wikipedia

    en.wikipedia.org/wiki/Acid_catalysis

    Many acids can function as sources for the protons. Acid used for acid catalysis include hydrofluoric acid (in the alkylation process), phosphoric acid, toluenesulfonic acid, polystyrene sulfonate, heteropoly acids, zeolites. Strong acids catalyze the hydrolysis and transesterification of esters, e.g. for processing fats into biodiesel. In ...

  9. Chemistry - Wikipedia

    en.wikipedia.org/wiki/Chemistry

    A substance can often be classified as an acid or a base. There are several different theories which explain acid–base behavior. The simplest is Arrhenius theory, which states that an acid is a substance that produces hydronium ions when it is dissolved in water, and a base is one that produces hydroxide ions when dissolved in
