EQUIVALENT SOLUTIONS. Section I. EQUIVALENT WEIGHT. 4-1 INTRODUCTION a. A gram equivalent weight by definition is the mass of substance that will combine with or displace one mole of hydrogen. b. In solutions of ionic compounds, the compound dissociates into positive or negative ions to react with other ions.

4 Jul 2008 Mole concept is based on molecular weight. An equivalent concept is gram equivalent weight or gram equivalent concept. It is based on equivalent 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

Equivalent weight is a term which has been used in several contexts in chemistry. In its most general usage, it is the mass of one equivalent, that is the mass of a given substance which will. combine or displace directly or indirectly with 1.008 parts by mass of hydrogen or 8 parts by mass of oxygen or 35.5 parts by mass of
Abstract—In this letter, we propose to introduce the notion of equivalent capacitance and to generalize the so-called equivalent- thickness concept to model arbitrary shapes of lightly doped nonplanar multigate MOSFETs, without the need to introduce any unphysical parameter. These definitions, which merely map.

Therefore the equivalent weight of chlorine is 35.5. However, hydrogen combines directly with only a few elements. On the other hand, oxygen combines directly with most of the elements. Therefore, oxygen was chosen as a standard for assigning equivalent weights to elements. MOLE CONCEPT. A chemist needed a unit
