Here, 1 / f eq is an integer value. Each solute can produce one or more equivalents of reactive species when dissolved. In redox reactions, the equivalence factor describes the number of electrons that an oxidizing or reducing agent can accept or donate. Here, 1 / f eq can have a fractional (non-integer) value.
An equivalent (symbol: officially equiv; [1] unofficially but often Eq [2]) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount (typically one mole) of another substance in a given chemical reaction. It is an archaic quantity that was used in chemistry and the biological sciences (see Equivalent weight § In ...
In organic chemistry, a cross-coupling reaction is a reaction where two different fragments are joined. Cross-couplings are a subset of the more general coupling reactions. Often cross-coupling reactions require metal catalysts. One important reaction type is this:
potassium permanganate has a molar mass of 158.034(1) g mol −1, and reacts with five moles of electrons per mole of potassium permanganate, so its equivalent weight is 158.034(1) g mol −1 /5 eq mol −1 = 31.6068(3) g eq −1. Historically, the equivalent weights of the elements were often determined by studying their reactions with oxygen.
Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...
This ratio of 1.19 obeys the law because it is a simple fraction (1/3) of 3.58. (This is because it corresponds to the formula ICl 3, which is one known compound of iodine and chlorine.) Similarly, hydrogen, carbon, and oxygen follow the law of reciprocal proportions. The acceptance of the law allowed tables of element equivalent weights to be ...
1,1'-Carbonyldiimidazole (CDI) is an organic compound with the molecular formula (C 3 H 3 N 2) 2 CO. It is a white crystalline solid . It is often used for the coupling of amino acids for peptide synthesis and as a reagent in organic synthesis .
I'd like to suggest three things 1.One example can be appended following the two indented definition. The example I found in one book is as follows: 6e-+14H + +Cr 2 O 7 2--> 2Cr 3+ + 7H 2 O In this example, 1 equivalent of K 2 Cr 2 O 7 is said to be one sixth of a mole( and I think it may be said that 1 mole of K 2 Cr 2 O 7 is 6 equivalents, though I have not verified whether an s should be ...
