This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
Acetic acid is monobasic because it has one dissociable hydrogen ion and combines with one hydroxyl ion of the base to give a single salt and water.
Does acetic acid is a monobasic acid?
Complete answer:
Acidity is defined as the tendency of any molecule to donate a proton in water easily. … We can see that it gives off only one H+ ion when added to the water. Hence, acetic acid is termed monobasic acid.
How will you show that acetic acid is monobasic?
When acetic acid is reacted with sodium hydroxide solution, only one H atom of the acid gets replaced and the product is sodium acetate and water This shows that acetic acid is a monobasic acid.
Why is acetic acid a monobasic acid though it contains 4 hydrogen atoms?
Acetic acid is called monobasic because it contains only one replaceable hydrogen atom per molecule.
Is acetic acid monobasic or dibasic?
Organic acids like Formic acid (HCOOH), Acetic acid (CH3COOH), Benzoic acid (C6H5COOH) are all monobasic. (ii) Dibasic acid : Dibasic acid contains two replaceable hydrogen atoms in a molecule.
Which compound is not a monobasic acid ?
21 related questions found
Is vinegar a monobasic acid?
Hence an acid that contains only one replaceable hydrogen atom in its molecule is known as a monobasic acid and its basicity is 1. … The household vinegar consists of Acetic acid as a primary ingredient.
What is the formula of acetic acid?
Acetic acid , systematically named ethanoic acid , is an acidic, colourless liquid and organic compound with the chemical formula CH3COOH (also written as CH3CO2H, C2H4O2, or HC2H3O2).
Why is the acidity of CH3COOH not 4?
Acetic acid has 4 hydrogens. It donates only one H, which is attached to Oxygen, Other 3 H are attached to Carbon, there is not much difference iof electronegativity in C and H in acetic acid so these 3 H can not be released.
Is hydrochloric acid monobasic?
Relating to an acid that contains only one hydrogen atom that can be replaced in an acid-base reaction. Hydrochloric acid (HCl) and nitric acid (HNO3 ) are monobasic acids.
Is acetic acid dibasic?
Example: Hydrochloric acid, nitric acid, acetic acid. Dibasic acid- Dibasic acids are acids that furnish two hydrogen ions (H+) per molecule in water. … Example: Phosphoric acid, phosphorus acid.
What do you understand by acetic acid?
: a colorless pungent liquid acid C2H4O2 that is the chief acid of vinegar and that is used especially in synthesis (as of plastics)
What do you understand by the statement acetic acid?
Acetic acid is a monobasic acid which on ionization in water produce one hydronium ion per molecule of the acid.
What is monobasic acid give example?
Monobasic acids are acids that can replace or lose only one hydrogen atom. Some of the examples of monobasic acids are nitric acid, hydrochloric acid and periodic acid. It is a weak monobasic acid, it can accept one hydroxide ion from a water molecule, when water is added to boric acid.
Is h2so4 a monobasic acid?
Sulphuric acid is dibasic acid, because it contains two hydrogen atoms which ionise in aqueous solution to become 2H+ ions.
Why is dilute HCl stronger than highly concentrated acetic acid?
HCl is a strong acid, CH3COOH is a weak acid. Strong and weak acid refer to the degrees of dissociation. HCl acid ionises completely to H+ and Cl– ions (that is, about 100 out of 100 molecules donate their hydrogen ion). … Hence, dilute HCl acid is stronger than highly concentrated acetic acid.
What is the basicity of acetic acid?
-In acetic acid, CH3COOH, there is only one ionizable hydrogen, which is attached to oxygen. As we see here that only one hydrogen ion releases so, it’s basicity is one although it has four hydrogen atoms. Hence, the basicity of acetic acid is 1.
Why is hydrochloric acid monobasic in nature?
Basicity of an acid is the number of hydronium ions formed by one molecule of the acid in its aq. solution. … Hence, a monobasic molecule has solely one replaceable hydrogen atom. Monobasic acids ionize in water to give only one H+ ion per acid molecule.
Is H2CO3 a monobasic acid?
Answer: H2CO3 is a Dibasic Acid. Explanation: It is also known as Carbonic acid.
Why Oxalic acid is called dibasic acid?
Dibasic acids: – There are two ionisable hydrogen atoms present in each molecule of dibasic acids. Example- Sulphuric acid, Oxalic acid. … The basicity of the molecule is the number of acidic hydrogen atoms.
Does a higher pH mean more acidic?
pH is a measure of how acidic/basic water is. The range goes from 0 – 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. … Water with a pH of five is ten times more acidic than water having a pH of six.
Is acetic acid a polar solvent?
Liquid acetic acid is a hydrophilic (polar) protic solvent, similar to ethanol and water. With a moderate relative static permittivity (dielectric constant) of 6.2, it dissolves not only polar compounds such as inorganic salts and sugars, but also non-polar compounds such as oils as well as polar solutes.
Which one of the following will not produce acid with water?
Carbon monoxide does not react with water to form an acid.
What is the pH of acetic acid?
So, now we know that a 1 M acetic acid solution has a pH of 2.38.
Is acetic acid harmful?
Effects on Humans: In vapor form, acetic acid is a severe irritant of the eyes, mucous membranes, upper respiratory tract, and skin. In contact with the skin or eyes, acetic acid solutions of 80% or more can be corrosive, causing severe burns of any exposed tissue.
