How do you find the gram equivalent weight of an acid and a base?

Equivalent weights may be calculated from molar masses if the chemistry of the substance is well known: sulfuric acid has a molar mass of 98.078(5) g mol−1, and supplies two moles of hydrogen ions per mole of sulfuric acid, so its equivalent weight is 98.078(5) g mol−1/2 eq mol−1 = 49.039(3) g eq−1.

How do you calculate equivalent weight of a base?

The equivalent weight of an element is its gram atomic weight divided by its valence (combining power).

How will you find out the equivalent mass of an acid give example?

Equivalent mass of an acid is the number of parts by mass of the acid which contains 1.008 part by mass of replaceble hydrogen atom. For example, the basicity of sulphuric acid is 2. which contains one replaceable hydroxyl ion or which completely neutralises one gram equivalent of an acid.

What is the equivalent weight of acid?

The equivalent weight of an acid is the mass of acid required to generate one mole of hydrogen (hydronium) ion in aqueous solution. For an acid like HCl, which has only one ionizable hydrogen, the equivalent weight is the same as the molar mass.

How do you find the equivalent weight of an acid?

The equivalent masses of acids, bases, and salts are calculated as follows:

1. Equivalent mass of an acid = molecular mass of the acid/basicity.
2. Equivalent mass of a base = molecular mass of the base/acidity.
3. Equivalent mass of a salt = molecular mass of the salt/total positive valency of metal atoms.

How do you calculate equivalent acidity?

Equivalent Acidity:The amount of CaCO3 required to neutralise the acid residues caused by acidic fertilizers in the soil e.g:100kg(NH4)2SO4 produces acidity which needs 110kg of CaCO3 to neutralise it. Therefore equivalent acidity of(NH4)2SO4 is 110;Anhydrous NH3 has more equivalent acidity than other fertilizers.

How to calculate the equivalent weight of an acid?

The equivalent weight of acid is calculated by dividing its molecular weight by the number of ionizable hydrogen. for hydroxides, divide by the number of hydroxyls. This is very useful in preparing solutions because solutions of the same normality (N) react completely volume (V) by volume. It is an old and practical way for titration purposes.

What does equivalent weight mean in chemistry?

Definitions of Equivalent Weight ( Acid-Base Context ) 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 the equivalent weight of H2SO4 in grams?

98.07 g/mol H2SO4 * (1 mole H2SO4 / 1 equivalent of H+) = 98.07g/equivalent of H+. In this example, the magnitude of the equivalent weight of sulfuric acid is the same as the molecular weight. This is beacuse according to the balanced chemical reaction, one mole of sulfuric acid reacts with ONE equivalent of hydroxide.

What is the equivalent weight of sulfuric acid in grams?

Theoretical Equivalent weight of sulfuric acid (H2SO4) = 49.03 g/equivalent of H+. Reasoning: 98.07 g/mol H2SO4 * (1 mole H2SO4 / 2 equivalents of H+) = 49.03 g/equivalent of H+. In this example, the magnitude of the equivalent weight of sulfuric acid is HALF of that of the molecular weight.
