How to determine equivalents chemistry?

in this type, spectroscopy is used to determine the equivalence point if the spectrum of the reactant, product or titrant is known. A specific amount of the product and reactant is used to find the equivalence point. A very low level of the free titrant’s presence can also be determined.

How do you find the equivalent mass?

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.

What is equivalent formula?

The equivalent of any substance is given by the charge it carries on itself. Thus, the equivalent weight is obtained by the ratio of the molar mass of the substance and the number of equivalents. It can be mathematically represented as. Equivalent weight = Molar Mass number of equivalents .

What is known as equivalent mass?

Equivalent mass: The number of parts by mass of a substance that combines with or displaces 1.008 parts by mass of hydrogen or 8.0 parts of oxygen or 35.5 parts of chlorine is called its equivalent mass (EM).

What is equivalent mass with example?

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. 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. ).

How do you find the equivalent mass for Class 11?

equivalent mass of an element is defined as the number of parts by mass of an element which combines with or displaces directly or indirectly. 1.008 parts by mass of hydrogen or 8 parts by mass of oxygen or 35.5 parts by mass of chlorine.
