What is the difference between gram equivalent and mole?
Mole concept is based on molecular weight. Equivalent weight is measure of mass proportion of an element, compound or ion in which it combines with the mass of other chemical entities. Mass of one gram equivalent, like its mole counterpart, is equal to mass in gram, which is numerically equal to equivalent weight.
What do equivalents mean in chemistry?
Illustrated Glossary of Organic Chemistry – One equivalent. One equivalent: In reaction stoichiometry, the amount of one substance that reacts with one mole of another substance. This will often (but not always) be a 1:1 mole ratio.
What is meant by mole equivalent?
The equivalent is formally defined as the amount of a substance (moles) which will react with 6.022 x 1023 electrons. (This is Avogadro’s Number, which is the number of particles in a mole).
What is number of equivalent?
The number of equivalents is a number that defines how many electrons or ions may be transferred in a chemical reaction.
What is the difference between gram equivalent and equivalent?
The key difference between gram equivalent and equivalent weight is that gram equivalent describes that the mass of one equivalent is given in the unit of gram whereas equivalent weight describes the mass of one equivalent in any unit of measurement.
Is gram equivalent same as N factor?
Gram equivalent for an element is numerically equal to the product of its n-factor and given number of moles. Where ‘n’ is the combining factor. For example for acids, it denotes the Basicity and for a base it denotes the Acidity.
What is mole into N factor?
We can divide n-factor calculation is two category. In case of non-redox reaction. n factor of oxidizing or reducing agent=change in oxidation number per molecule. An equivalent is defined as the amount of an acid that contains one mole of H+ ions or the amount of a base that contains one mole of OH- ions.
What is the formula of equivalent?
Equivalent equations are algebraic equations that have identical solutions or roots. Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation. Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.
How do you calculate equivalency?
To calculate molar equivalents for each reagent, divide the moles of that reagent by the moles of the limiting reagent: Note that the molar equivalency of sodium benzoate is 1. This is because sodium benzoate is the limiting reagent. Any reagents used in excess will have a molar equivalency greater than one.
What equivalence mean?
Definition of equivalence 1a : the state or property of being equivalent. b : the relation holding between two statements if they are either both true or both false so that to affirm one and to deny the other would result in a contradiction. 2 : a presentation of terms as equivalent.
