Chapter 7: Problem 1

State whether the following statements are true or false. Electrolysis brings about a chemical change.

Short Answer

Expert verified
Answer: True.

Step by step solution

01

Define Electrolysis

Electrolysis is the process in which an electric current is passed through an electrolyte (a substance that conducts electricity), causing the ions in the electrolyte to move. This motion of ions results in the separation of ions, leading to the production of new substances at the electrodes (the positive and negative terminals).
02

Understand Chemical Change

A chemical change is a change that occurs in which one or more substances are transformed into new substances with different chemical properties from the original substances. Chemical changes usually involve the formation or breaking of chemical bonds.
03

Determine if Electrolysis Causes Chemical Change

As mentioned in Step 1, electrolysis causes the ions in the electrolyte to move and form new substances at the electrodes. This indicates new chemical bonds are being formed, and therefore, a chemical change occurs during electrolysis.
04

State Whether the Statement is True or False

Since electrolysis brings about a chemical change, as demonstrated by the formation of new substances at the electrodes, the statement "Electrolysis brings about a chemical change" is true.
