2. Brønsted–Lowry acid–base theory - Wikipedia

   en.wikipedia.org/wiki/Brønsted–Lowry_acid...

   t. e. The Brønsted–Lowry theory (also called proton theory of acids and bases[ 1 ]) is an acid–base reaction theory which was first developed by Johannes Nicolaus Brønsted and Thomas Martin Lowry independently in 1923. [ 2 ][ 3 ] The basic concept of this theory is that when an acid and a base react with each other, the acid forms its ...

4. 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.

5. Lewis acids and bases - Wikipedia

   en.wikipedia.org/wiki/Lewis_acids_and_bases

   Acids and bases. A Lewis acid (named for the American physical chemist Gilbert N. Lewis) is a chemical species that contains an empty orbital which is capable of accepting an electron pair from a Lewis base to form a Lewis adduct. A Lewis base, then, is any species that has a filled orbital containing an electron pair which is not involved in ...

8. DNA and RNA codon tables - Wikipedia

   en.wikipedia.org/wiki/DNA_and_RNA_codon_tables

   DNA and RNA codon tables. The standard RNA codon table organized in a wheel. A codon table can be used to translate a genetic code into a sequence of amino acids. [1] [2] The standard genetic code is traditionally represented as an RNA codon table, because when proteins are made in a cell by ribosomes, it is messenger RNA (mRNA) that directs ...

9. HSAB theory - Wikipedia

   en.wikipedia.org/wiki/HSAB_theory

   HSAB is an acronym for "hard and soft (Lewis) acids and bases ". HSAB is widely used in chemistry for explaining the stability of compounds, reaction mechanisms and pathways. It assigns the terms 'hard' or 'soft', and 'acid' or 'base' to chemical species. 'Hard' applies to species which are small, have high charge states (the charge criterion ...
