Question

15. Within a voltaic cell,___
takes place at the anode, electrons flow to the cathode, where____
takes place.
A. reduction; current
B. oxidation; reduction
C. reduction; oxidation
D. oxidation, current

Answer 1

Answer:

B. oxidation; reduction

Explanation:

A voltaic cell is electro-chemical cell in which chemical energy is converted into electrical energy.

1. This cell utilizes chemical reaction to generate electric.\

2. there two electrode anode and cathode

3. At Anode oxidation occurs

4. At cathode reduction occurs

5. chemical is present in the cell which is electrolyte which completes the circuit of the voltaic cell.

• oxidation is the process in which there is loss of electrons
• Reduction is the process in which there is gain of electrons

___________________________________________________

Based on above discussion

At anode oxidation takes place

At cathode reduction takes place.

Hence, correct option is B. oxidation; reduction

Answer 2

Question:

In a voltaic cell, the ____________ electrons and is oxidized, while the ___________ electrons and is reduced.

Answers:

1. anode loses

2. cathodes gains

Explanation:

Oxidation - what happens when a reactant loses electrons.

Reduction - occurs when a reactant gains electrons.
