evaporate/heat it till crystallization point. Obtain dry crystals.

@adi tixic i still think that we have some error  in the series..
we missed carbon look at the change i did:
Please               Potassium
Send                 Sodium
Cows                 Calcium
Monkeys             Magnesium
And                   Aluminium
Caribbean           Carbon
Zebras               Zinc
In                     Iron
Large                 Lead
Hard                  Hydrogen
Cages with         Copper
Maximum            Mercury
Security             Silver
Guards               Gold
please...             Platinum

i feel now there must be no more changes!!! :P :P :P :P

By the way...u guyz missed the working of hydrogen fuel cells with acid electrolyte..

heres. it..

the hydrogen (H2) loses electrons.. 2H2 --> 4H+ + 4e- which travel through the circuit to the cathode and react with O2..also the H+ ions from the acid electrolyte meets the electrons and O2 at the cathode

the reaction

O2 + 4H+ + 4e- = 2H2O

---
The H+ ions removed from the electrolyte are replaced by those produced at the anode.

@adorabledaughter - yea..ut u can use the word heat and crystallization point.

sry..i 4got this..

anode - -ve terminal
cathode = +ve terminal
