--- End quote ---
evaporate/heat it till crystallization point. Obtain dry crystals.
adorabledaughter_07:
Thanks ..u cud evaporate it alzo rite...bt ans scheme doest grant a mark 4 it...

@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.
