A strong electrolyte and a weak electrolyte :
Sr.No. | Characteristics | Strong electrolyte | Weak electrolyte |
1 | Dissociation into ions in aqueous solution. | Almost complete | Partial and not much |
2 | Species present in solution. | Almost only free ions | Both ions and undissociated molecules. |
3 | Number of ions present in solution. | Very large | Only limited in numbers |
4 | Quantity of current conducted | Large amounts, a bulb glows brightly | Only small amounts, a bulb glows dimly |
5 | Examples | HCl, NaOH, NaCl | CH3COOH, NH4OH. |
