What is meant by equivalent mass?

The equivalent mass of an element, compound or ion is the number of parts of mass of an element which combines with or displaces 1.008 parts of hydrogen or 8 parts of oxygen or 35.5 parts of chlorine.

What does equivalent of solute mean?

As per the standard definition, normality is described as the number of gram or mole equivalents of solute present in one litre of a solution. When we say equivalent, it is the number of moles of reactive units in a compound.

How do you find the gram equivalent mass of a solute?

Gram equivalent weight is equal to mass in grams numerically equal to Equivalent Weight. To calculate the Gram Equivalent Weight, we use the formula Eq = MW / n.

How do you find the equivalent of a solute?

EW is the equivalent weight in g/equivalent. It is calculated by dividing the molecular weight of solute by the number of equivalents per mole of solute (Equation 2). For acids, the number of equivalents per mole is the number of H+ ions contributed by the acid per mole of acid.

What is equivalent mass of salt?

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.

Is equivalent mass and equivalent weight same?

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.

What is equivalent weight in chemistry?

equivalent weight, in chemistry, the quantity of a substance that exactly reacts with, or is equal to the combining value of, an arbitrarily fixed quantity of another substance in a particular reaction. The equivalent weight of an element is its gram atomic weight divided by its valence (combining power).

What is equivalent mass in electrochemistry?

The Electrochemical equivalent, sometimes abbreviated Eq or Z, of a chemical element is the mass of that element (in grams) transported by 1 coulomb of electric charge. The electrochemical equivalent of an element is measured with a voltameter.

What is gram equivalent mass 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. These values correspond to the atomic weight divided by the usual valence; for oxygen as example that is 16.0 g / 2 = 8.0 g.

What is equivalent weight of salt?

The valence of NaCl is 1. Equivalent Weight = Molecular weight/ Valency. = 58.44 / 1 = 58.44 g/mol. Therefore, the equivalent weight of sodium chloride (NaCl) is 58.44 g/mol. Explore more such questions and answers at BYJU’S.
