Question

In the galvanic cell, true statement(1) Current flows from anode to cathode(2) Anode is +ve terminal(3) If Ecel<0, it is a spontaneous reaction(4) Cathode is +ve terminal​

Answer 1

Answer:

In a galvanic (voltaic) cell, the anode is considered negative and the cathode is considered positive. This seems reasonable as the anode is the source of electrons and cathode is where the electrons flow.

However, in an electrolytic cell, the anode is taken to be positive while the cathode is now negative. However, the reaction is still similar, whereby electrons from the anode flow to the positive terminal of the battery, and electrons from the battery flow to the cathode.

Answer 2

Hi there,

♧ Answer are 1 & 4

◇ Explanation

- In galvanic cell :

☆ Anode is the negative pole at which oxidation process occures

☆ Cathode is the positive pole at which reduction process occures

☆ Current flow from anode to cathode

☆ E.cell is more than zero (+ve)

☆ Reaction is spontaneuos
