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.
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.
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 ...
22 Σεπ 2021 · The objectives of this experiment are to perform an analytical titration, to standardize a basic solution, and to determine the equivalent mass of an unknown acid.
Definitions of Equivalent Weight ( Acid-Base Context ) The weight of a compound that contains ONE EQUIVALENT of a proton (for acid) or ONE EQUIVALENT of an hydroxide (for base). Examples: (1) H 2 SO 4 + 2OH-= 2H 2 O + SO 4 2-Molecular weight of sulfuric acid (H 2 SO 4) = 98.07 g/mol
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).
