Question

The apparatus given in the adjoining figure was set up to demonstrate electrical conductivity. Which of the following statement(s) is(are) correct? (i) Bulb will not glow because electrolyte is not acidic. (ii) Bulb will glow because HCl is a strong acid and furnishes ions for conduction. (iii) Bulb will not glow because circuit is incomplete. iv) Bulb will not glow because it depends upon the type of electrolytic solution.

i and iii

ii and iv

ii only

iv only​

Answer 1

Answer:

the correct answer is 2) bulb will glow bcoz hcl is strong acid and furnishes ions for condiction

Explanation:

hope it helps

plz mark my answer as brainliest

Answer 2

The bulb will glow because HCl is a strong acid and furnishes ions for conduction. Thus, the second statement is correct. (Option 3)

• As the bulb connects to the setup, the bulb will glow as HCl provides it with the required ions for conduction and thus, produce electricity.
• Had we used any weaker acid other than HCl, the bulb might have glowed dimly or would have not even lit up.
• That is because any other weaker acid does not provide the setup with adequate ions required for conduction.
