What is the equivalent weight of a compound?
Equivalent Weight. The weight of a compound that contains ONE EQUIVALENT of a proton (for acid) or ONE EQUIVALENT of an hydroxide (for base). In this example, the magnitude of the equivalent weight of sulfuric acid is HALF of that of the molecular weight.
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.
How do you calculate equivalent?
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.
How do you find equivalent weight?
The equivalent weight of an element is its gram atomic weight divided by its valence (combining power).
How do you calculate equivalent weight?
What is the unit of equivalent weight?
The 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 atomic weight 1.008 (rounded to three decimal places) and always assumes valence 1 in compounds, so its equivalent weight is 1.008.
How do you find the equivalent weight of HCl?
Now equivalent mass is given as the molecular weight divided by the n-factor. Therefore, the equivalent mass of HCl is 85.1g.
What is equivalent weight of NaCl?
58.44 g/mol.
Therefore, the equivalent weight of sodium chloride (NaCl) is 58.44 g/mol.
What is the equivalent weight of HCl?
The equivalent weight of an acid or base for neutralization reactions or of any other compound that acts by double decomposition is the quantity of the compound that will furnish or react with or be equivalent to 1.008 g of hydrogen ion or 17.0074 g of hydroxide ion—e.g., hydrochloric acid (HCl), 36.461 g; sulfuric …
What is the equivalent weight of an element?
equivalent weight. The equivalent weight of an element or radical is equal to its atomic weight or formula weight divided by the valence it assumes in compounds. The 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.
How to find atomic weight of all the elements of periodic table?
Mouseover on the chart to see the element name and Atomic Weight of the element. This Atomic Weight chart table gives the Atomic Weight of all the elements of periodic table . Click on ‘Element Atomic Number’, ‘Element Symbol’, ‘Element Name’ and ‘Element Atomic Weight’ headers to sort.
How do you calculate equivalent weight of a compound?
Additionally, the equivalent weight of a compound can be calculated by dividing the molecular mass by the number of positive or negative electrical charges that result from the dissolution of the compound.
What is the equivalent weight of hydrogen in grams?
The 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 atomic weight 1.008 (rounded to three decimal places) and always assumes valence 1 in compounds, so its equivalent weight is 1.008.
