Question

What is the equivalent weight formula?

Answer 1

Hint: We know that the equivalent weight (otherwise called gram equivalent) is the mass of one same that is the mass of a given substance which will consolidate with or uproot a fixed amount of another substance. The same load of a component is the mass which consolidates with \[1.008\] grams of hydrogen or \[8.0\] grams of oxygen or \[35.5\] grams of chlorine.

Complete answer:
In science, the equivalent weight of a compound arrangement is characterized as the proportion of the atomic load of the solute to the valency of the solute. The equivalent weight of the substance will change, and it relies upon the kinds of responses it goes through. It is for the most part used to anticipate the mass of the substance which responds with the one iota of hydrogen in the corrosive base examination. Likewise, the ordinariness of the arrangement can be determined utilizing the same weight. It implies that the ordinariness of the synthetic arrangement is characterized as the quantity of the same load of any substance disintegrated in the one liter of arrangement. The recipe to figure the same weight is given as:
\[{\text{Equivalent}}Weight = \dfrac{{Molecular Weight}}{{Valency}}\]
For instance, think about the response,
\[{H_3}P{O_4} \to HPO_4^{2 - } + 2{H^ + }\]
The molecular weight of a substance response is \[98\] , and the valency is two, then, at that point the equivalent weight of \[{H_3}P{O_4}\] is
$Equivalent Weight = \dfrac{{98}}{2} = 49$
Accordingly, the equivalent weight of \[{H_3}P{O_4}\] is \[49\] .

Note:
We know that Equivalent weight has the measurements and units of mass, in contrast to nuclear weight, which is dimensionless. Comparable loads were initially controlled by analysis, yet (to the extent that they are as yet utilized) are presently obtained from molar masses. Furthermore, the same load of a compound can be determined by partitioning the atomic mass by the quantity of positive or negative electrical charges that outcome from the disintegration of the compound.
