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 ...
Normality is defined as the number of gram or mole equivalents of solute present in one liter of solution.The SI unit of normality is equivalents per liter (Eq/L). = where N is normality, m sol is the mass of solute in grams, EW sol is the equivalent weight of solute, and V soln is the volume of the entire solution in liters.
In chemistry, equivalent weight (also known as gram equivalent [1] or equivalent mass) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance.
Epoxy value derives from the Epoxy equivalent weight (EEW) or Weight Per Epoxide (WPE) and is a measure of the epoxy content of an epoxy resin or epoxy reactive diluent, or glycidyl ether. [1] This is an important parameter as it allows determination of the correct mix ratio of an epoxy system with a curing agent. [ 2 ]
The equivalence point, or stoichiometric point, of a chemical reaction is the point at which chemically equivalent quantities of reactants have been mixed. For an acid-base reaction the equivalence point is where the moles of acid and the moles of base would neutralize each other according to the chemical reaction.
In analytical chemistry, ... The value may also be used to calculate equivalent weight and if the functionality is known, the molecular weight also. [7]
From January 2008 to December 2012, if you bought shares in companies when William P. Fricks joined the board, and sold them when he left, you would have a -21.9 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
The acceptance of the law allowed tables of element equivalent weights to be drawn up. These equivalent weights were widely used by chemists in the 19th century. The other laws of stoichiometry are the law of definite proportions and the law of multiple proportions. The law of definite proportions refers to the fixed composition of any compound ...
