question 4 (2 points)
identify the substance that is a weak electrolyte.
○nano₃
○naoh
○nh₃
○ca(oh)₂
○hi

Explanation:

Strong electrolytes dissociate completely in solution. $NaNO_3$ is a soluble salt, $NaOH$ is a strong base, $Ca(OH)_2$ is a strong base (although slightly soluble), and $HI$ is a strong acid. $NH_3$ is a weak base and only partially ionizes in water, making it a weak electrolyte.

Answer:

C. $NH_3$
