Question

which of the following compounds is a weak electrolyte?
hno₃
nano₃
hno₂
nano₂
naoh

Explanation:

Strong electrolytes dissociate completely in solution. $HNO_3$ is a strong acid and dissociates completely. $NaNO_3$ and $NaNO_2$ are salts that dissociate completely into ions. $NaOH$ is a strong base and dissociates completely. $HNO_2$ is a weak acid and only partially dissociates in solution, making it a weak - electrolyte.
