According to Henderson–Hasselbalch Equation,
pH = pKa + log [Acetate] / [Acetic Acid]
As,
pKa = -log Ka
pKa = -log (1.8 × 10⁻⁵)
pKa = 4.74
So,
pH = 4.74 + log [Acetate] / [Acetic Acid]
4.34 = 4.74 + log [Acetate] / [Acetic Acid]
4.34 - 4.74 = log [Acetate] / [Acetic Acid]
-0.40 = log [Acetate] / [Acetic Acid]
Taking Antilog on both sides,
[Acetate] / [Acetic Acid] = 0.398
There must be an intramolecular force. The oxygen atoms are produced as a result of the breakdown of oxygen molecules. Intramolecular force is necessary to stop the oxygen (O2) in the air from changing into the O atom.
Which force causes attraction between O2 molecules?
The result is the London dispersion force, a fleeting attractive attraction, which is created when the electrons in two neighboring atoms occupy positions that temporarily cause the atoms to form dipoles. This interaction is commonly described by the phrase "induced dipole-induced dipole attraction".
What is the difference between intramolecular forces and intermolecular forces which type is stronger?
In general, intramolecular forces are greater than intermolecular forces. Ion-dipole interaction exerts the strongest intermolecular force, followed by hydrogen bonds, dipole-dipole interaction, and London dispersion. Examples. Hydrogen bonding forces, London dispersion forces, and dipole-dipole forces are the three different kinds of intermolecular interactions. The three different kinds of intramolecular forces are metal bonds, ionic bonds, and covalent bonds.
