  2. Neutralization (chemistry) - Wikipedia

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

    An example of a base being neutralized by an acid is as follows. Ba(OH) 2 + 2 H + → Ba 2+ + 2 H 2 O. The same equation relating the concentrations of acid and base applies. The concept of neutralization is not limited to reactions in solution. For example, the reaction of limestone with acid such as sulfuric acid is also a neutralization ...

  3. Alkali salt - Wikipedia

    en.wikipedia.org/wiki/Alkali_salt

    The difference between a basic salt and an alkali is that an alkali is the soluble hydroxide compound of an alkali metal or an alkaline earth metal. A basic salt is any salt that hydrolyzes to form a basic solution. Another definition of a basic salt would be a salt that contains amounts of both hydroxide and other anions. White lead is an ...

  4. Basic oxide - Wikipedia

    en.wikipedia.org/wiki/Basic_oxide

    For example, the basic oxide Li 2 O becomes the hydroxide LiOH, and BaO becomes Ba(OH) 2 after reacting with water. In contrast, non-metals usually form acidic oxides . In general, the basicity of oxides increases when towards the lower-left corner of the periodic table , which corresponds to increased metallic properties.

  5. Salt metathesis reaction - Wikipedia

    en.wikipedia.org/wiki/Salt_metathesis_reaction

    A neutralization reaction is a type of double replacement reaction. A neutralization reaction occurs when an acid reacts with an equal amount of a base. 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

  6. Acid salt - Wikipedia

    en.wikipedia.org/wiki/Acid_salt

    The solution is expected to be neutral only when K a = K b. [12] Other possible factors that could vary pH level of a solution are the relevant equilibrium constants and the additional amounts of any base or acid. For example, in ammonium chloride solution, NH + 4 is the main influence for acidic solution.

  7. Base (chemistry) - Wikipedia

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

    A reaction between aqueous solutions of an acid and a base is called neutralization, producing a solution of water and a salt in which the salt separates into its component ions. If the aqueous solution is saturated with a given salt solute, any additional such salt precipitates out of the solution.

  8. Acid–base extraction - Wikipedia

    en.wikipedia.org/wiki/Acid–base_extraction

    Acid–base extraction is a subclass of liquid–liquid extractions and involves the separation of chemical species from other acidic or basic compounds. [1] It is typically performed during the work-up step following a chemical synthesis to purify crude compounds [2] and results in the product being largely free of acidic or basic impurities.

  9. Standard solution - Wikipedia

    en.wikipedia.org/wiki/Standard_solution

    In titrations, the concentration of analyte in solution can be determined by titrating the standard solution against the analyte solution to determine the threshold of neutralization. [9] For example, to calculate the concentration of hydrogen chloride, a standard solution of known concentration, such as 0.5 M sodium hydroxide, is titrated ...
