How do you tell what is the most acidic molecule?
Water molecule is one of the most stable substances known. How do we know which proton is the most acidic in a molecule (such as acetic acid) that contains more than one type of proton? Remember that the higher the degree of positive character on the proton, the more acidic it is.
Which molecule is most acidic?
Proton
ANSWER: Proton (a) is the most acidic.
Is nahco3 an acid or base?
Sodium bicarbonate is a weak base with pH slightly above 7.
Which is most acidic phenol?
p-nitro phenol
Hence, p-nitro phenol is most acidic among the given.
Which compound is more acidic?
The closer the negative ion is to the H+ ion in the molecule, the stronger the acid is. Look at the strengths in the bonds between the molecules in the ion. The more lopsided it is throughout the molecule, the stronger the acid. A molecule with a triple bond is more acidic than one that only has single bonds.
How many acidic protons are there in CH3COOH?
(i) Acetic Acid, n-factor=1, and moreover, Resonance between the delivers 1 proton, or . (ii) Sulphuric acid, n-factor=2. (iii) Sodium Carbonate, no protons. (iv) Sodium Hydrogen-carbonate delivers 1 proton in basic medium.
Why is acetic acid acidic?
The hydrogen centre in the carboxyl group (−COOH) in carboxylic acids such as acetic acid can separate from the molecule by ionization: CH3COOH ⇌ CH3CO2− + H. Because of this release of the proton (H+), acetic acid has acidic character. Acetic acid is a weak monoprotic acid.
Is Sulphuric acid highly viscous?
Sulphuric acid is highly viscous in nature because its molecules are associated with hydrogen bonding. It is a highly corrosive chemical. It is also used as a sulphonating agent in organic reactions.
What is sulfuric acid?
Sulfuric acid is a sulfur oxoacid that consists of two oxo and two hydroxy groups joined covalently to a central sulfur atom. It has a role as a catalyst. It is a conjugate acid of a hydrogensulfate.
Why is sulphuric acid stronger than hydrogen?
So it is always the hydrogen that makes the acid. The acid is stronger if the remaining molecule, often a negative ion, can deal very well with the negative charge; this is certainly the case for the hydrogen sulphate group that remains from sulphuric acid.
What is the concentration of sulfuric acid at boiling point?
Grades of sulfuric acid. 3 at the boiling point brings the concentration to 98.3\% acid. The 98.3\% grade is more stable in storage, and is the usual form of what is described as “concentrated sulfuric acid”.
What is the pKa of sulfuric acid at 25 degrees Celsius?
The pKa of sulfuric acid is 1.92 at 25 °C (1), indicating that this compound will exist almost entirely in anion form in the environment. Sulfuric acid dissociates readily in water to form sulfate ions and hydrated protons; at pH 3.92 the dissociation is 99\% (1).
