Equivalent mass of copper

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. The equivalent weight of an element is the mass which combines with or displaces 1. These values correspond to the atomic weight divided by the usual valence ; [2] for oxygen gas as example that is Equivalent weight has the units of mass, unlike atomic weight , which is now used as a synonym for relative atomic mass and is dimensionless. Equivalent weights were originally determined by experiment, but insofar as they are still used are now derived from molar masses. The equivalent weight of a compound can also be calculated by dividing the molecular mass by the number of positive or negative electrical charges that result from the dissolution of the compound. The first equivalent weights were published for acids and bases by Carl Friedrich Wenzel in John Dalton 's first table of atomic weights suggested a reference point, at least for the elements : taking the equivalent weight of hydrogen to be one unit of mass. One of the greatest problems was the reaction of hydrogen with oxygen to produce water.

In the last few articles, we have studied the hydrogen displacement method, oxide formation method, reduction method, chloride formation method, and double displacement method to determine the equivalent mass of metal. The equivalent mass of a substance is the number of parts by mass of the substance which combines with or displaces or contains 1. If the equivalent mass is expressed in grams then it is called gram equivalent mass GEM.
