Question

Of the following solutions, which one is expected to be the weakest electrolyte?

• A. $HCI\left(aq\right)$
• B. $HF\left(aq\right)$
• C. $NaOH\left(aq\right)$
• D. $KI\left(aq\right)$
• E. $HCI{O}_4\left(aq\right)$

Answer 1

The correct option is B $HF\left(aq\right)$

$HF\left(aq\right)$ is expected to be the weakest electrolyte. All others are strong electrolytes.Weak electrolytes partially dissociate in aqueous solution. Strong electrolytes completely dissociate in aqueous solution.
