    Caustic potash/caustic wood alkali – potassium hydroxide, formed by adding lime to potash. Caustic Soda/caustic marine alkali – sodium hydroxide, NaOH, formed by adding lime to natron. Caustic volatile alkali – ammonium hydroxide. Corrosive sublimate – mercuric chloride, formed by subliming mercury, calcined green vitriol, common salt ...

  3. Alkali - Wikipedia

    en.wikipedia.org/wiki/Alkali

    Alkalis are usually defined as a subset of the bases. One of two subsets is commonly chosen. A basic salt of an alkali metal or alkaline earth metal [2] (this includes Mg(OH) 2 (magnesium hydroxide) but excludes NH 3 ). Any base that is soluble in water and forms hydroxide ions [3] [4] or the solution of a base in water. [5]

  4. Base (chemistry) - Wikipedia

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

    A strong base is a basic chemical compound that can remove a proton (H +) from (or deprotonate) a molecule of even a very weak acid (such as water) in an acid–base reaction. Common examples of strong bases include hydroxides of alkali metals and alkaline earth metals, like NaOH and Ca(OH) 2, respectively. Due to their low solubility, some ...

  5. Alkali salt - Wikipedia

    en.wikipedia.org/wiki/Alkali_salt

    Alkali salts or base salts are salts that are the product of incomplete neutralization of a strong base and a weak acid. Rather than being neutral (as some other salts), alkali salts are bases as their name suggests. What makes these compounds basic is that the conjugate base from the weak acid hydrolyzes to form a basic solution.

  6. Metal hydroxide - Wikipedia

    en.wikipedia.org/wiki/Metal_hydroxide

    They consist of hydroxide (OH −) anions and metallic cations, [1] and are often strong bases. Some metal hydroxides, such as alkali metal hydroxides, ionize completely when dissolved. Certain metal hydroxides are weak electrolytes and dissolve only partially in aqueous solution.

  7. Alkali hydroxide - Wikipedia

    en.wikipedia.org/wiki/Alkali_hydroxide

    The solubility increases down the column as the alkali metal ions become larger and the lattice enthalpies decrease. [1] All alkali metal hydroxides are strong bases, meaning that they dissociate completely in solution to give OH − ions. As strong bases, alkali hydroxides are highly corrosive and are used in cleaning products.

  8. Lewis acids and bases - Wikipedia

    en.wikipedia.org/wiki/Lewis_acids_and_bases

    A Lewis base is also a Brønsted–Lowry base, but a Lewis acid does not need to be a Brønsted–Lowry acid. The classification into hard and soft acids and bases ( HSAB theory ) followed in 1963. The strength of Lewis acid-base interactions, as measured by the standard enthalpy of formation of an adduct can be predicted by the Drago–Wayland ...

    Lithium oxide (Li 2 O) is the lightest alkali metal oxide and a white solid. It melts at 1570 °C. Sodium oxide (Na 2 O) is a white solid that melts at 1132 °C and decomposes at 1950 °C. It is a component of glass. Potassium oxide (K 2 O) is a pale yellow solid that decomposes at 350 °C.
