They are classified as strong, weak, or non-electrolytes based on their ability to dissociate.<\/li>\n\n\n\n<li><strong>Strong Electrolytes:<\/strong><br>A strong electrolyte fully dissociates into its constituent ions in water, meaning the solution contains only ions and no undissociated molecules.
