Mnemonic for electrolysis
« on: May 30, 2009, 10:10:06 am »
Does anyone know a good mnemonic for the preference order for ions to be discharged in electrolysis?
A mnemonic is like an acronym for those who dont know.
Any chemistry mnemonics are actually welcome, especially the reactivity series ones.





AND WHY IS MY REP -8??????!!!!!!!!

yeah but theres an order kind of like the reactivity series for which ions are given out and which ones stay in the electrolyte.

here:
for cations reactivity series:
please-K
send-Na
cats-Ca
monkeys-Mg
and-Al
zebras-Zn
in-iron
large-lead
hired-H
cages-Cu
make-Hg
sure-Ag
padlocked-platinum

for anions:
someone -sulphate
only-hydroxide(gives oxygen on oxidation)
nice-nitrate
cleans-chloride
broken -bromide
items-iodide


for crude oil fractions:
please-petroleum gases
never - naphtha
kill-kerosene
dolphins-diesel oil
living-lubricating oil
bravely-bitumen

for litmus paper,here's how i avoid confusion:
            Be right back
    blue-red-blue
  blue-red(acid)  red-blue(base)

for solubilities,
PCB for sulphates (Pb-lead,Ca-calcium,Ba-barium)

i know some ppl who get confused with the electrodes; so here's 1

Cool, but the electrodes are already kinda embedded in my head, because i did a course in roots, and the prefix cat- means negative.

AHHHH WAIT A SECOND!!! MY BOOK SAYS THAT HYDROXIDE IS DISCHARGED AFTER NITRATES
So ill remember it as Someone Nice Only Cleans Broken Items.

Theres another 1 to remember the fractions

Rolling------Refinery gas
Guns-------Gasoline
Nearly------Naphtha
Killed-------Kerosene
Drunk-------Diesel oil
Funny------Fuel oil
Limping-----Lubricating oil
Robber------Residue

here's another one ... i usually get confused in whether oxidation occurs at cathode or electrode, so, i keep in my mind the 5th letters,like:

 oxidAtion - Anode
 reduCtion - Cathode

@thukon- yesss hydroxide is discharged in preference!!! thanx for reminding,so now it is some1 nice only cleans broken items ;D
