Question

HELP ME PLEASE. Which of the following statements is true for electrolysis? New atoms are created by destroying old atoms. A compound is heated to form multiple products. An electric current is used to synthesize a substance. An electric current is used to decompose a substance.

Answer 1

Answer:

An electric current is used to decompose a substance.

Explanation:

Concept tested: Electrolysis

We can answer the question by asking ourselves important questions

First; What is electrolysis?

• Electrolysis refers to the process through which molten or aqueous compound known as electrolytes are decomposed by passing electric current through them.

Second; What are electrolytes?

• Electrolytes are substances in either molten or aqueous form and are good conductors of electric current.

• Electrolytes are good conductors of electric current due to the presence of mobile ions.

Third: What happens during electrolysis?

• Electrolytes are therefore decomposed by passing electric current through them resulting to formation of new elements or molecules.
• For example, when molten sodium chloride is decomposed by passing electric current through it, sodium metal is released at the cathode while chlorine is released at the anode.
