Equivalent weight Definition & Facts Britannica
WebApr 7, 2024 · HCl → H + + Cl-The number of hydrogen ions or hydronium ions released by hydrochloric acid is one. So, the valency factor will be one. The molecular weight of hydrochloric acid = 36.45. As we know, Equivalent weight = molecular weight / X. The equivalent weight of hydrochloric acid = 36.45 / 1 = 36.45. For Bases. The reasoning … WebMar 8, 2024 · The general number of equivalents formula is. E = MW/charge number. Where MW is the molecular weight of the compound and charge number is the number of proton- or hydroxide-equivalents the compound … 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 because weighing errors are reduced. An example is the volumetric standardisation of a solution of sodium hydroxide which … 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the mass of polymer which corresponds … See more The use of equivalent weights in general chemistry has largely been superseded by the use of molar masses.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 chemistry of the substance is well known: • 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 analyte (the species of interest).
