Question

When an electric current is passed through a conducting solution, there is a change of color of the solution. This indicates

• A. The chemical effect of current.
• B. The heating effect of current.
• C. The magnetic effect of current.
• D. The lightning effect of current.

Answer 1

The correct option is A

The chemical effect of current.

The explanation for the correct option:

In the case of option A,

Conductivity

1. Electrical conductors are materials that facilitate the flow of electricity.
2. When we compare two types of materials, the first one is said to be a good conductor of electricity because it allows more electricity to flow through it.
3. The electric charges can easily pass via an electrical conductor. Conductivity is the ability of conductors to conduct electricity.
4. A chemical reaction occurs when an electric current runs through a conducting solution.
5. Electric current has a chemical effect on this.
6. When an electric current is utilized to conduct a solution, a chemical reaction occurs.
7. As a result of the chemical impact of electric current, a color shift occurs.
8. Because the color of the solution changes as the current passes through it, there must be a chemical reaction taking place inside the solution.
9. There is no change taking place in the heating, magnetic, and lighting effects.

Therefore, the correct option is A.
