2. Base (chemistry) - Wikipedia

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

   The equilibrium constant for this reaction at 25 °C is 1.8 x 10 −5, [12] such that the extent of reaction or degree of ionization is quite small. Lewis bases A Lewis base or electron-pair donor is a molecule with one or more high-energy lone pairs of electrons which can be shared with a low-energy vacant orbital in an acceptor molecule to ...

3. Acid neutralizing capacity - Wikipedia

   en.wikipedia.org/wiki/Acid_neutralizing_capacity

   Acid-neutralizing capacity or ANC in short is a measure for the overall buffering capacity against acidification of a solution, e.g. surface water or soil water.. ANC is defined as the difference between cations of strong bases and anions of strong acids (see below), or dynamically as the amount of acid needed to change the pH value from the sample's value to a chosen different value.

4. Alkalinity - Wikipedia

   en.wikipedia.org/wiki/Alkalinity

   Alkalinity (from Arabic: القلوية, romanized: al-qaly, lit. 'ashes of the saltwort') [1] is the capacity of water to resist acidification. [2] It should not be confused with basicity, which is an absolute measurement on the pH scale. Alkalinity is the strength of a buffer solution composed of weak acids and their conjugate bases.

5. Sodium hydroxide - Wikipedia

   Once initiated, the exothermic transformation is complete in a few minutes, with a 6.5% increase in volume of the solid. The β form can be crystallized from supercooled solutions at −26 °C, and melts partially at −1.83 °C. [17] The "sodium hydroxide" of commerce is often the monohydrate (density 1.829 g/cm 3). Physical data in technical ...

6. Universal indicator - Wikipedia

   en.wikipedia.org/wiki/Universal_indicator

   A universal indicator is a pH indicator made of a solution of several compounds that exhibit various smooth colour changes over a wide range pH values to indicate the acidity or alkalinity of solutions. A universal indicator can be in paper form or present in a form of a solution. [1]
