What does equivalent mean in chemistry?

What does equivalent mean in chemistry?

Illustrated Glossary of Organic Chemistry – One equivalent. One equivalent: In reaction stoichiometry, the amount of one substance that reacts with one mole of another substance. This will often (but not always) be a 1:1 mole ratio.

What is equivalent in physical chemistry?

It is defined as the number of equivalents of a solute present in one litre of solution. Equivalent is also the term used for amount of substance like mole with the difference that one equivalent of a substance in different reactions may be different as well as the one equivalent of each substance is also different.

What is equivalent concept?

Concept of equivalents. Equivalent mass of element. Number of parts by mass of an element which reacts or displaces from a compound 1.008 parts by mass. of hydrogen, 8 parts by mass of oxygen and 35.5 parts by mass of chlorine, is known as the equivalent.

How do you do equivalents in chemistry?

To calculate molar equivalents for each reagent, divide the moles of that reagent by the moles of the limiting reagent: Note that the molar equivalency of sodium benzoate is 1. This is because sodium benzoate is the limiting reagent. Any reagents used in excess will have a molar equivalency greater than one.

What is equivalent factor?

Equivalent factors are factors used to convert quantities from their original physical units into a common accounting unit for the purpose of aggregating energy sources or assessing contributions” to environmental problems from diverse sources (for example, the contribution of different pollutants to global warming).

What is equivalent formula?

Using the formula: Eq = MW / n. Eq = equivalent weight. MW = atomic or molecular weight in g/mol, from periodic table. n = no. of equivalents.

What is normality chemistry?

Normality is a measure of concentration equal to the gram equivalent weight per liter of solution. Gram equivalent weight is the measure of the reactive capacity of a molecule. The solute’s role in the reaction determines the solution’s normality. Normality is also known as the equivalent concentration of a solution.

What is equivalent mass in chemistry?

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.

How do you find an equivalent?

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.

What is equivalent fraction with example?

Equivalent fractions are fractions that represent the same value, even though they look different. For example, if you have a cake, cut it into two equal pieces, and eat one of them, you will have eaten half the cake.

What is number of equivalent?

The number of equivalents is a number that defines how many electrons or ions may be transferred in a chemical reaction.
