Question

The breaking down of a compound by passing electricity through it is known as

• A. electromagnetism
• B. electrolysis
• C. electronics
• D. ultrasound

Answer 1

Answer: (B)

The correct option is B electrolysis
Electrolysis is the process of breaking down of a compound into its constituent ions by passing electricity through it.

For example : When an electric current is passed through water $\left(H_{2}O\right)$, it decomposes into $O^{-2}$ and $H^{+}$ ions which get further converted into Oxygen $\left(O_2\right)$ and Hydrogen $H_2$, respectively.
