Electrochemistry Crossword Puzzle

QUESTIONS LIST:

• reduction : a gain of electrons (or decrease in oxidation number).
• cathode : the electrode where reduction occurs.
• oxidation number : a number representing the charge an atom would have if electrons were transferred completely; indicates oxidation state.
• endothermic : a reaction that absorbs heat from its surroundings.
• electrolysis : a process that uses electrical energy to drive a non-spontaneous chemical reaction.
• half equation : an equation showing either oxidation or reduction, including electrons.
• conductors : materials that allow the flow of electric charge.
• ionic equation : an equation showing only the ions and molecules involved in the reaction.
• oxidizing agent : a substance that causes oxidation by accepting electrons and is itself reduced.
• anode : the electrode where oxidation occurs.
• oxidation : a loss of electrons (or increase in oxidation number).
• overall equation : the balanced chemical equation for the complete reaction.
• reducing agent : a substance that causes reduction by donating electrons and is itself oxidized.
• electrolyte : an ionic compound that conducts electricity when molten or in solution.
• exothermic : a reaction that releases heat to its surroundings.
• electrodes : solid conductors that allow current to enter or leave an electrolyte.
