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 … See more The first equivalent weights were published for acids and bases by Carl Friedrich Wenzel in 1777. A larger set of tables was prepared, possibly independently, by Jeremias Benjamin Richter, … See more When choosing primary standards in analytical chemistry, compounds with higher equivalent weights are generally more desirable … See more In polymer chemistry, the equivalent weight of a reactive polymer is the mass of polymer which has one equivalent of reactivity (often, the mass of polymer which corresponds to one mole of reactive side-chain groups). It is widely used to indicate the … See more The use of equivalent weights in general chemistry has largely been superseded by the use of molar masses. Equivalent weights may be calculated from molar masses if the … See more The term “equivalent weight” had a distinct sense in gravimetric analysis: it was the mass of precipitate which corresponds to one gram of See more WebSep 27, 2024 · Since 4 grams of hydrogen react with 32 grams of oxygen, so 1 gram of hydrogen will react with 8 grams of oxygen. So the equivalent weight of oxygen is 8. H 2 + Cl 2 → 2HCl. Since 2 grams of hydrogen react with 71 grams of chlorine, the equivalent weight of chlorine is 35.5.

WebIt can be mathematically represented as. Equivalent weight = Molar Mass number of equivalents . The number of equivalents implies the charge carried by the compound. For example: For Ca ( OH) 2, the number of equivalents is 2 as the charge on Ca is 2+ and 2 equivalents of ( OH -) is present. The molecular formula of calcium hydroxide is = Ca (OH)2. WebMar 31, 2024 · Definition: Gram equivalent mass of an element, compound or ion is the mass that combines or displaces 1.008 g hydrogen or 8 g oxygen or 35.5 g chlorine. … readymade software

Webweight of oxygen (W. Equivalent weight (E w) Formula: W = (w2 - w1) grams. E w = [w2 / (w2 - w1)] * atomic weight of oxygen. This is an ../Chemistry Calculator that calculates … WebThe unit of equivalent weight is the atomic mass unit; the amount of a substance in grams numerically equal to the equivalent weight is called a gram equivalent. Hydrogen has … WebWeight of metal= x gm and weight of oxide= y gm∴ Oxygen consumed= (y−x) gmSince (y−x) gm of oxygen combines with x gm of metal∴8gm of oxygen will combine with y−x8x gm of metalHence equivalent weight of metal= y−xx ×8. readymade suits for gents
