Question 1 Report

Which of the following particles conduct electricity through salty water?
Answer Details
Particles that conduct electricity through salty water are called ions. When salt is dissolved in water, it dissociates into positively charged ions (such as sodium ions) and negatively charged ions (such as chloride ions). These ions are able to move freely in the water, carrying an electric charge and allowing an electric current to flow through the solution. In contrast, atoms and molecules do not conduct electricity in water because they do not have a net electric charge and are not able to move freely. Electrons and neutrons are subatomic particles that can be found in atoms, but they are not able to move freely in water and therefore cannot conduct electricity in this medium. Therefore, the correct option is "Ions".
