Question

$\huge \mathfrak \red { \underline {Good morning}}$

Can you help me with this question plz ???​

Answer 1

Answer:

C..... is the correct answer

Answer 2

Explanation:

In the given apparatus, we can see that:

• Electrolyte used in a dilute and strong acid known as hydrochloric acid.
• Two electrodes are connected as a source of current flow in the circuit.
• The circuit is absolutely correct and the switch is also closed. There is no breaking in between the wires.

We have to conclude which of following sentences are correct and which are not. So, let's see the sentences:

(I) Bulb will not glow because electrolyte is not acidic.

• The electrolyte taken above is dilute solution of HCl, so it is acidic in nature. Being an strong acid, it ionise itself completely when dissolved in water. So this is incorrect.

(ii) Bulb will glow because HCl is a strong acid and furnishes ions for conduction.

• HCl completely ionised when dissolved in water and hence provides ions which conduct electricity. As we are getting source, the currents willf low and the bulb will also glow. So this is correct.

(iii) Bulb will not glow because circuit is incomplete.

• No there is no gap or break in any part of the electric circuit, it means current will complete it's path and bulb will glow. So, this is incorrect.

(iv) Bulb will not glow because it depends upon the type of electrolytic solution.

• Yes it will depend upon the electrolytic solution but here it is strong acid and hence provide a lot of free ions which will inturn flow the current inside the circuit. Hence this is also incorrect.

On the basis of our above explanation and views, we can say that the only correct one in the statements is:

$\huge{ \boxed{ \sf{ \red{(ii) \: only}}}}$

Option C

And we are done !!
