Define a salt bridge. a pathway by which counter ions can flow between the half-cells without the solutions in the half-cell totally mixing. a pathway in which no ions flow. a pathway, composed of salt water, that ions pass through. a pathway between the cathode and anode in which ions are reduced. a pathway between the cathode and anode in which ions are oxidized.

A pathway by which counter ions can flow between the half-cells without the solutions in the half-cell totally mixing.

Explanation:

Electrochemical cell -

Device used for the conversion of chemical energy to electrical energy is called electrochemical cell.

it is based on oxidation reduction reaction.

Electrolyte is a solvent in which ions are dissolved and two electrodes are dipped in it.

Anode electrode is responsible for oxidation, and the cathode electrode is responsible for reduction.

The electrochemical cell is composed of two electrodes dipped in an electrolyte , and which are further connect by salt bridge .

Salt bridge firstly connects the circuit and allows the movement of ions and , resists any mixing of the solution , and helps to maintain the electrical neutrality condition .

Hence , from the question , the correct option about salt bridge is the first option .

a is the answer to this question

explanation:

the answer is definitely c.
