Question

Order the following compounds from least conductivity to high conductivity :

HCl-NaCl-NaOH-CH3COOH-CH3COONa

Answer 1

Conductivity of an electrolyte is the measure of its ability to conduct electricity.

Strong electrolytes are the electrolytes which dissociate completely in solution and weak electrolytes are the electrolytes which do not dissociate fully in solution.

In the following molecules given above the highest conductivity is of the HCl molecule because H+ has a abnormally high conductivity due to the proton jump.H+ and OH- have a very high conductivity due to their abnormal behavior.

The order of the following compounds from least conductivity to high conductivity is:

1.HCl(strong acid) H+ is small in size so it moves very fast and has high conductivity

2.NaOH(strong base) Na+ is large in size so moves slowly

3.NaCl(salt)

4.CH3COOH(weak acid)

5.CH3COONa(salt)

The strong electrolytes are the strong acids, strong bases and salts whereas the weak electrolytes are the weak acids and weak bases
