Questions and Answers

What is electrochemistry?

  • The area of Chemistry dealing with the interconversion of electrical energy and chemical energy (correct)
  • The process of creating electricity from chemical reactions
  • The study of metals and their properties
  • The production of metals through electrolysis

What does a negative EΘ in the electrochemical series indicate?

  • The redox couple is a good conductor of electricity
