Sodium ions, Na2+
4. In an electrochemical cell, what is electrolytes and state the function?
A. The substance in molten or aqueous to allow electric current to flow through them and undergo chemical changes.
B. Electric conductor that connected to the battery.
C. To measure electric
5. Which of the following substances can be used as an electrolyte in electrolysis?
A. Ethanol
B. Ester
C. Distilled water
D. Sodium chloride solution
6. Why is sodium chloride not able to conduct electricity in a solid state?
Ion move freely
Solid sodium chloride contains sodium ions
Sodium ions and chloride ions are held together by the strong electrostatics force caused them not to move freely
Sodium ions receive electrons to form a metal and chloride ions lose electrons to form chlorine gas
