Why ethanoic acid ahas a lower conductivity than hydrochloric acid?

Answer 1

Formic acid is a smaller molecule as compare to acetic acid so polarity is working in small area and O-H bond is more polar HCOOH, in acetic acid the additional CH3- group is an electrons donor group so O-H bond is little bit stronger and less polar so it is weaker acid.

Answer 2

Because it ionises less in solution. HCl separates almost completely in solution to form the ions Cl- and H+. Acetic acid only partially ionises into CH3COO- and H+ with lots of it staying as complete CH3COOH molecules. It is the concentration of ions in a solution which determines its conductivity. An electric current passes through the solution by movement of these ions. The extent to which any partially ionised substance actually ionises can be expressed as its pKa value.

Answer 3

Chlorine when attached to alpha carbon of acetic acid it attracts electrons due to high electronegativity and makes 'O-H' bond weaker through inductive effect so removal of proton becomes easier.

Answer 4

It isn't

The acid dissociation constant pKa at standard conditions for HCl is -8 and for acetic acid is 4.76. This means that in equal molar solutions (say, of 1M each) of HCl and acetic acid, there will be much more (about 5 million times) hydronium ions (dissolved H+) in the HCl standard solution than the acetic acid standard solution. In fact, in this solution while nearly all the HCl will be dissociated, at any given moment, less than 1% of the acetic acid will be dissociated.

Answer 5

Ethanoic acid has a lower conductivity than hydrochloric acid because hydrochloric acid is very acidic more so than ethanoic acid meaning hydrochloric acid has a lower pH level, in turn hydrochloric acid is a strong acid, while ethanoic acid is a weaker acid.

Answer 6

Because it does not contain any ions. Acetic acid is a covalent bond (share electrons), and not an ionic bonds (generally good conductors of electricity).

Answer 7

pure acetic acid has fully ionized, but dilute actic acid is incomplete in ionization, so there are ions present, which means charged particles are present and able to conduct electricity

Answer 8

HCl is a stronger acid, it dissociates completely in water and the ions conduct electricity

Answer 9

Because it does not disassociate completely. Only about 1% of the molecules in solution ionize, so the conduction of electricity is weak.
