Formation - THE ENERGY CHANGE WHEN
1 moles of a compound is formed from its elements
in their standard states
Hydration - when
one mole of gaseous ions
is completely surrounded by water
Solution -
when one of an ionic compound
is completely dissolved in water

produces a voltage
because of the difference in
reactivity of two half-cells
