30 sty 2023 · Equivalent weight is the ratio of molecular mass and valence factor. It can be calculated by knowing the valence factor for acids and bases, which are the number of replaceable hydrogen and hydroxyl groups, respectively.
8 mar 2020 · 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 contains. Examples with different acids and bases help illustrate how this works in practice.
The equivalent masses of acids, bases, and salts are calculated as follows: Equivalent mass of an acid = molecular mass of the acid/basicity. Equivalent mass of a base = molecular mass of the base/acidity. Equivalent mass of a salt = molecular mass of the salt/total positive valency of metal atoms.
In chemistry, equivalent weight (also known as gram equivalent[1] or equivalent mass) 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.
This document provides a summary of common positive and negative ions, compounds, and their chemical formulas and equivalent weights. It lists the chemical formula, number of equivalents, and equivalent weight for over 70 positive and negative ions and compounds.
25 cze 2016 · Equivalent weight is defined as “ The number of parts by weight of any element that combine with (or displace) directly or indirectly, 1.008 parts by weight of Hydrogen or 8 parts by weight of oxygen or 35.5 parts by weight of chlorine.” Lets illustrate some examples: C+ O 2 → CO 2.
24 sty 2016 · The formula you were talking about gives the equivalent weight of an element (can be extended to be used with ions). Equivalent weight = (Atomic mass)/(Valency) This could be intuitive and obvious for some.
