Answer:
i=2 for HCl and i=1 for ethanol
Step-by-step explanation:
Hello,
Since the hydrochloric acid is composed by sodium and chloride ions which are completely dissociated, two types of ions are present, that's why i becomes 2.
On the other hand, as long as the ethanol doesn't present dissociation in aqueous solution, the Van't Hoff factor becomes 1.
Best regards.
