Equivalent Weight in chemistry (1) Like atomic weight and molecular weight, equivalent weight is also a number, it does not have any unit. (2) The weights of the substances that take part in a chemical reaction and the substances formed from it are in the ratio of their equivalent weights. This is called the law of chemical equilibrium. The number of moles of an acid or base multiplied by the number of hydrogens or hydroxides that a molecule has to contribute in a neutralization reaction is called the number of equivalents of that substance. Basically, the number of effective neutralizing moles available determines the ratio of acid to base in a neutralization reaction.

The rest for the conversion into alcohol. E.g. iii) Benzoic acid requires 3 equivalents of DIBAL-H for its conversion into benzyl alcohol. Water Chemistry CaCO3 Equivalents. Multiply the mg/l of the substances listed below by the corresponding factors to obtain mg/l as CaCO3. For example, 70 mg/l of Mg + + would be (70) (4.10) = 287 mg/l as CaCO3. Equivalent-Mass of Salts: Equivalent mass of a simple salt is that mass of it which contains one gram equivalent of the metal or a radical. Illustration - 1: Molecular mass of KCl = 39 + 35.5 = 74.5. In this case, KCl contains 1 gram equivalent of K and 1 gram equivalent of Cl. Hene equivalent mass of KCl is 74.5 / 1 = 74.5.

Equivalent Weight. The amount of substances that completely react with each other in the reaction is called equivalent weight in chemistry. Equivalent weight = molecular weight / X. In the above formula X represents the valency factor. Eg: Sulphuric Acid (H2SO4) For acids, X (valency factor) is the basicity. What is equivalent in organic chemistry?

Similarly, CaCl 2 separates into three ions per molecule of solute (1 Ca + and 2 Cl -) and thus has a valence of 3. This leads to the definition of an equivalent, or specifically a. Chemistry questions and answers Define "equivalent" as it relates to solution concentration. Question : Define "equivalent" as it relates to solution concentration. The equivalent mass of a substance is the number of parts by mass of the substance which combines with or displaces or contains 1.008 parts by mass of hydrogen, 8 part by mass of oxygen, or 35.5 part by mass of chlorine. If the equivalent mass is expressed in grams then it is called gram equivalent mass (GEM). Illustration:.

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. What is equivalent concept?. What is equivalent in chemistry? An equivalent (symbol: officially equiv; unofficially but often Eq) 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. .... Definition: Gram equivalent mass is defined as the mass of an element (compound or ion) that combines or displaces 1.008 g hydrogen or 8 g oxygen or 35.5 g chlorine. In this reaction 1 mole of zinc (i.e. 65.38 g) displaces one mole of hydrogen molecule (2.016 g). Equivalent mass has no unit but gram equivalent mass has the unit g eq -1. A molar equivalent is the ratio of the moles of one compound to the moles of another. Once you determine the moles (or mmols) of each compound you can determine the molar equivilants. Usually you are relating the moles of the limiting reagent to the moles of other starting materials or reagents used in the reaction. Cold Spring Harbor Laboratory (CSHL) invites applications for a Postdoctoral Research Fellow in Anticancer Drug Discovery.

Carbon–sulfur (C–S) bond formation is one of the important synthetic routes in organic chemistry. Among sulfur sources for C–S bond formation, organosulfur cations (RS+) and their synthetic equivalents are unique reagents. These cationic sulfur species are easily prepared as compared with the oxonium analogues, because of their low ionization potentials. This review describes.

Equivalent Weight in chemistry (1) Like atomic weight and molecular weight, equivalent weight is also a number, it does not have any unit. (2) The weights of the substances that take part in a chemical reaction and the substances formed from it are in the ratio of their equivalent weights. This is called the law of chemical equilibrium. Ac­cord­ing to the clas­si­cal def­i­ni­tion, an equiv­a­lent of a sub­stance is a con­di­tion­al or real par­ti­cle that can be equiv­a­lent in any way to a cation of hy­dro­gen in ion ex­change and acid-base re­ac­tions, or to an elec­tron in re­dox re­ac­tions. In chemistry, equivalent weight (also known as gram equivalent) 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 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. one thousandth (10−3) of a chemical equivalent (see equivalent weight ).
