Equivalent Weight. We define the equivalent weight of a substance (element or compound) as: "The number of parts by weight of it, that will combine with or displace directly or indirectly 1.008 parts by weight of hydrogen, 8 parts by weight of oxygen, 35.5 parts by weight chlorine or the equivalent parts by weight of another element".
Best Answer: You will be calculating equivalent weights of acids, bases, and salts. So the rule is to divide the molecular weight of an acid by the number of replaceable H atoms; divide the molecular weight of a base by the number of OH groups; and divide the molecular weight of a salt by the number of H's or OH's that reacted to form it.
Equivalent weight of Oxidising and Reducing Agents. Equivalent weight of a substance (oxidant or reductant) is equal to molecular weight divided by number of electrons lost or gained by one molecule of the substance in a redox reaction.
Define equivalent weight. equivalent weight synonyms, equivalent weight pronunciation, equivalent weight translation, English dictionary definition of equivalent weight. n. The weight of a substance that will combine with or replace one mole of hydrogen or one-half mole of oxygen.
The equivalent weight of NaCl is the same as the molecular weight which is 40. For example, to prepare a 1N NaCl solution you need to dissolve 40g of NaCl in 1000mL of water. You can also use the formula Normality= weight of substance in Grams* 1000/ equivalent weight*volume required in mL.
Equivalent weight depends on type of the substance. For example, Equivalent weight of acid = molecular weight of acid/basicity of acid The acid H2SO4 can donate 2 hydrogens.
Titrimetry Calculation Example: Calculate the percentage of acid if it takes 20.5ml of 0.085N NaOH to titrate a 10ml sample of a juice, the total titratable acidity of that juice is expressed as percent citric acid. (molecular weight = 192, equivalent weight = 64).
Equivalent weight definition is - the mass of a substance especially in grams that combines with or is chemically equivalent to eight grams of oxygen or one gram of hydrogen : the atomic or molecular weight divided by the valence.
The Equivalent Weight Calculator(Acid) an online tool which shows Equivalent Weight (Acid) for the given input. Byju's Equivalent Weight Calculator(Acid) is a tool which makes calculations very simple and interesting. If an input is given then it can easily show the result for the given number.
Equivalent weight of acid Calculation. The number of replaceble hydrogen atoms present in the molecule of an acid is Basicity of acid.This Acid Weight Calculator is used to calculate the estimated weight of acid.
Equivalent Weight. Equivalent weight isn't really a weight-- it's a mass.Mass is the amount of matter in something, while weight is the gravitational pull on a mass. Since we're only dealing with ...
Equivalent weight: Equivalent weight of the substance is defined as the weight of the substance that contains or reacts with 1.0078 g of hydrogen or 8 g of oxygen, or 35.45 g of chlorine. This generalized definition is used for the calculation of equivalent weight. But depending upon the reaction involved,
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
English examples for "equivalent weight" - It could carry 12 fully equipped troops or the equivalent weight in equipment. This also allows them to sustain a higher metabolic rate than most equivalent weight mammals. These figures, therefore, represent the equivalent weights of these elements.
Hence, equivalent weight of N a H C O 3 is (23 + 1 + 12 + 3X16)/1 = 84. If we look at the defining ratio of equivalent weight of a compound (AB) formed of two radicals (say A and B), then we can rearrange the ratio as : Equivalent weight, E =
Fee Calculation Examples Fee Calculation For Pick Ups or Vehicles Operation at an Unladen Weight of 10,000 Pounds or Less. Total California Registration Fee = Unladen Weight Fee + Registration Fee + VLF Apportioned Registration Fee = Total California Registration Fee x California Mileage Percentage. Example 1 Vehicle with Two Axles Registration ...
The normality of a solution is the gram equivalent weight of a solute per liter of solution. It may also be called the equivalent concentration. It is indicated using the symbol N, eq/L, or meq/L (= 0.001 N) for units of concentration. For example, the concentration of a hydrochloric acid solution might be expressed as 0.1 N HCl.
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 grams of oxygen or 35.5 grams of chlorine.
The equivalent weight of any substance is the mass of the substance in grams that combines with or is chemically equivalent to eight grams of oxygen or one gram of hydrogen. In other words, it is equal to the mass of the substance in grams that would react with or replace one gram of hydrogen.
In science, the equivalent weight of a solution is the molecular weight of the solute, or dissolved substance, in grams divided by the valence of the solute. Equivalent weight predicts the mass of a substance that will react with one atom of hydrogen in an acid-base analysis such as a titration.
Equivalent weight definition: the weight of an element or compound that will combine with or displace 8 grams of oxygen... | Meaning, pronunciation, translations and examples
Equivalent Weight. The equivalent weight (eq. wt.) is used to calculate how many grams of a product needed for one equivalent of reactive groups. For an isocyanate, the reactive group is -N=C=O (NCO. Its concerntration is measured by weight percent NCO.
Chemists use equivalent units, or equivalents, to express the contribution of an acid or base to the total acidity or alkalinity of a solution. To calculate the pH of a solution--the measure of a solution's acidity--you need to know how many hydrogen ions are present in the solution.
GUIDE TO URETHANE CALCULATIONS. Equivalent weight The equivalent weight (eq.wt) tells you how many grams of a product you need to have for one equivalent of reactive groups. . For an isocyanate, the reactive group is –N=C=0 (NCO), and its concentration is measured by weight percent N
How To Calculate Normality & Equivalent Weight For Acid Base Reactions In Chemistry - Duration: 16:49. The Organic Chemistry Tutor 188,349 views. 16:49.
Calculate equivalent weight Divide the molecular weight by the number of hydrogen protons it donates as acid or the number of hydroxide (OH)- anions it produces as a base. Use the units of grams per equivalent of H+ or grams per equivalent of (OH)-, depending on the ion species the molecule donates to the reaction.
The equivalent weight of an element or radical is equal to the ratio of it's atomic weight or formula weight devided by it's valency.
