How do you find the equivalent of a compound?
To calculate the equivalent mass of a base, simply divide the molar mass of the base by the number of hydroxyl groups. Take, for example, calcium hydroxide Ca(OH)₂. A few simple calculations yield an equivalent of 37g/mol. To find the equivalent of an acid, divide the acid’s molar mass by the number of protons.
Why do we calculate equivalent weight?
Equivalent weight is used in the calculation of normality. The normality of a solution is defined as the number of gram equivalents of the solute present per litre of the solution. It is represented by the symbol, N.
What is equivalent weight of NaCl?
58.44 g/mol.
Therefore, the equivalent weight of sodium chloride (NaCl) is 58.44 g/mol.
How do you get an equivalent fraction?
To find the equivalent fractions for any given fraction, multiply the numerator and the denominator by the same number. For example, to find an equivalent fraction of 3/4, multiply the numerator 3 and the denominator 4 by the same number, say, 2. Thus, 6/8 is an equivalent fraction of 3/4.
How do you calculate NaCl equivalent?
The sodium chloride equivalent is correctly calculated using the following formula: Sodium (mg) × 2.54 ÷ 1,000 = Salt content (g). Sodium content is sometimes expressed in grams.
How do you find the equivalent weight of a disproportionation reaction?
For disproportionation reactions, use a trick to find equivalent mass; E = E1 + E2; where E1 and E2 are equivalent masses of oxidation and reduction half reactions of same element. Now, find the n-factor(total change in oxidation number per molecule) and then equivalent mass = molar mass/n-factor.
What is the equivalent weight of k2 cr2 o7?
Equivalent weight of K2Cr2O7 is 49 g/mol.
How do you find the equivalent weight of a compound?
The equivalent weight of a compound is the molecular weight of the compound divided by the net positive valence: First I’ll show you how to determine the molecular weight of a compound. Let’s start with an easy one: sodium hydroxide (NaOH), for instance:
What does equivalent weight mean?
Equivalent Weight Definitions of Equivalent Weight ( Acid-Base Context ) The weight of a compound that contains ONE EQUIVALENTof a proton (for acid) or ONE EQUIVALENTof an hydroxide (for base). Examples: (1)H2SO4+ 2OH-= 2H2O + SO42-
What is the molecular weight of a compound?
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 2SO 4 + 2OH -= 2H 2O + SO 4 2-. Molecular weight of sulfuric acid (H 2SO 4) = 98.07 g/mol.
What is equequivalent weight in chemistry?
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. You can calculate it easily, as long as you know the molecular weights of the compounds involved in the reaction.
