  2. Ate complex - Wikipedia

    en.wikipedia.org/wiki/Ate_complex

    The phrase -ate ion or ate ion can refer generically to many negatively charged anions. -ate compound or ate compound can refer to salts of the anions or esters of the functional groups. Chemical terms ending in -ate (and -ite ) generally refer to the negatively charged anions , neutral radicals , and covalently bonded functional groups that ...

    Nick Brit the Camel ate an Inky Clam with Crêpes for Supper in Phoenix. Number of consonants denotes number of oxygen atoms. Number of vowels denotes negative charge quantity. Inclusion of the word "ate" signifies that each ends with the letters a-t-e. To use this for the -ite ions, simply subtract one oxygen but keep the charge the same.

  4. Polyatomic ion - Wikipedia

    en.wikipedia.org/wiki/Polyatomic_ion

    As the number of oxygen atoms bound to chlorine increases, the chlorine's oxidation number becomes more positive. This gives rise to the following common pattern: first, the -ate ion is considered to be the base name; adding a per-prefix adds an oxygen, while changing the -ate suffix to -ite will reduce the oxygens by one, and keeping the suffix -ite and adding the prefix hypo-reduces the ...

    According to their properties, cations are usually classified into six groups. [1] Each group has a common reagent which can be used to separate them from the solution.To obtain meaningful results, the separation must be done in the sequence specified below, as some ions of an earlier group may also react with the reagent of a later group, causing ambiguity as to which ions are present.

    When a salt of a metal ion, with the generic formula MX n, is dissolved in water, it will dissociate into a cation and anions. [citation needed]+ + (aq) signifies that the ion is aquated, with cations having a chemical formula [M(H 2 O) p] q+ and anions whose state of aquation is generally unknown.

  7. Isomorphous replacement - Wikipedia

    (SO 4) 2. 12H 2 O, where A was a monovalent metallic ion (NH4 +, K +, Rb +, Cs +, or Tl +), B was a trivalent metallic ion (Al 3+, Cr 3+, or Fe 3+) and S was usually sulfur, but could also be selenium or tellurium. Because the alum crystals were largely isomorphous when the heavy atoms were changed out, they could be phased by isomorphous ...

  8. Hofmeister series - Wikipedia

    en.wikipedia.org/wiki/Hofmeister_series

    The denaturing of proteins by an aqueous solution containing many types of ions is more complicated as all the ions can act, according to their Hofmeister activity, i.e., a fractional number specifying the position of the ion in the series (given previously) in terms of its relative efficiency in denaturing a reference protein.

  9. Specific ion interaction theory - Wikipedia

    en.wikipedia.org/wiki/Specific_ion_interaction...

    where z is the electrical charge on the ion, I is the ionic strength, ε and b are interaction coefficients and m and c are concentrations. The summation extends over the other ions present in solution, which includes the ions produced by the background electrolyte. The first term in these expressions comes from Debye–Hückel theory.
