What is equivalent weight of acid equal to?

What is equivalent weight of acid equal to?

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 find the equivalent weight of K2Cr2O7?

Calculate equivalent weight of K2Cr2O7 in acidic medium. = 294 g/mol. Now, putting these values in above formula of equivalent weight: \[Equivalent{\text{ }}weight = \dfrac{{294}}{6} = 49g/eq\]. Hence, the equivalent weight of ${K_2}C{r_2}{O_7}$ in acidic medium will be 49g/eq.

What is the equivalent weight of K2Cr2O7 in acidic medium?

Equivalent weight of K2Cr2O7 in acidic medium is 49 g/mol. Hope this helps you.

Is formic acid and methanoic acid the same?

formic acid (HCO2H), also called methanoic acid, the simplest of the carboxylic acids, used in processing textiles and leather. Pure formic acid is a colourless, fuming liquid with a pungent odour; it irritates the mucous membranes and blisters the skin. It freezes at 8.4 °C (47.1 °F) and boils at 100.7 °C (213.3 °F).

Is formic acid strong or weak?

Formic acid is a weak acid and hydrochloric acid is a strong acid.

Are methanoic acid and formic acid the same?

How do you make methanol formic acid?

In this process, methanol is oxidized to formaldehyde by alcohol oxidase and catalase, followed by the formaldehyde dismutase reaction that leads to the formation of methanol and formic acid.

What is the equivalent weight of CaCO3?

50.045
The equivalent weight of calcium carbonate (CaCO3) is 50.045, as calculated above.

What is the formula for equivalent weight?

Equivalent Weight = Molecular weight/ Valency Also, read: Chemical Reaction.

What is the equation of formic acid?

Formula and structure: The chemical formula of formic acid is HCOOH or HCO2H. Its molecular formula is CH 2O 2 and its molar mass is 46.02 g/mol.

Is methanoic acid different from formic acid?

The key difference between formic acid and acetic acid is that formic acid (or methanoic acid, HCOOH) contains a carboxylic acid group attached to a hydrogen atom whereas acetic acid (or ethanoic acid, CH 3 COOH) has a methyl group attached to a carboxylic acid. Both formic acid and acetic acid are simple carboxylic acids.

What is the KB of ClO4?

Transcribed Image Text from this Question. BH+ClO4- is a salt formed from the base B (Kb = 1.00 times 10-4) and perchloric acid. It dissociates into BH+, a weak acid, and ClO4-, which is neither an acid nor a base.

What is ka in Chem?

An acid dissociation constant, Ka, (also known as acidity constant, or acid-ionization constant) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction known as dissociation in the context of acid–base reactions.
