Chapter 15: Electrolysis

fuel cells

Like ________, electrolyzers consist of an anode and a cathode separated by an electrolyte.

aqueous electrolytes

When ________ are involved, electrolysis is slightly more complicated.

Electrolysis

________ is the process of using electricity to split water into hydrogen and oxygen.

Electrolytes

________ are aqueous or molten.

metal element

If the ________ formed is less reactive than hydrogen, then the metal is produced at the cathode.

compound

When a(n) ________ is dissolved in water, the resulting solution has water present.

Water molecules

________ can split into two ions: hydrogen ions (H+) and hydroxide ions (OH)-

hydrogen ion

The ________ and the metal ion are attracted to the cathode.

hydroxide ions

The ________ and halide ions are attracted to the anode.

Metal reactivity

________ is compared to hydrogen.

Electrolysis

________ is a promising option for carbon- free hydrogen production from renewable and nuclear resources.

Aqueous electrolytes

________ contain water.

Water molecules can split into two ions

hydrogen ions (H+) and hydroxide ions (OH-)

Half equations

A half reaction is either the oxidation or reduction reaction component of a redox reaction.

Solution

In chemistry, a solution is a special type of homogeneous mixture composed of two or more substances.

Extracted

remove or take out, especially by effort or force
