19 Απρ 2024 · Equivalent weight is the mass of a substance that combines with or is equivalent to eight grams of oxygen or one gram of hydrogen in a chemical reaction. How is equivalent weight calculated? It is calculated by dividing the molecular weight by the valence (number of electrons transferred per molecule in the reaction).
An equivalent weight which is also known as gram equivalent can be defined as is the mass of one equivalent, that is the mass of a given substance that will combine with or displace a fixed quantity of another substance.
Equivalent weight. Number of parts by mass of an element which reacts or displaces from a compound 1.008 parts by mass of hydrogen or 8 parts by mass of oxygen or 35.5 parts by mass of chlorine, is known as the equivalent weight of that element. Example: Find the equivalent weight of for its oxide formation. Answer: From the above equation we ...
29 Ιουλ 2021 · 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. Consider the following reaction: Zn + H 2 SO 4 → ZnSO 4 + H 2. In this reaction 1 mole of zinc (i.e. 65.38 g) displaces one mole of hydrogen molecule (2.016 g).
Equivalent weight focuses on the reactive capacity of a substance, while gram equivalent emphasizes the weight of a substance that is chemically equivalent to one mole of hydrogen ions or hydroxide ions.
The equivalent weight of an element is the mass of a mole of the element divided by the element's valence. That is, in grams, the atomic weight of the element divided by the usual valence. [2] For example, the equivalent weight of oxygen is 16.0/2 = 8.0 grams.
20 Σεπ 2021 · The Gram equivalent (or equivalent weight) can be defined as the mass of an element that combines with or displaces 1.008 grams of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. Gram equivalent is a more relevant concept when working with acid and bases.
