Hey guys I really struggle to remember these does anyone have any decent ways to remember them?

Im glad u asked a cation is a flat cat _ meaning its negative -
and the anion is the opposite

 

[1981Grant]

I know that. I'm talking about testing for cations and anions with precipitates and flame tests. Can you help with that at all?

 

[zombies]

CATion - reference to a cat has got many lives which is positive therefore anion must be negative.

I always thought of it as the 't' in 'cation' being like a plus sign =P

I have exactly the same problem you are, i am going to try and finish memorising them tonight (by rote) and if i come up with a method to help i will post it

Lead is aloner, he's too fat and (heavy metal) and so is chloride, he bloody smells, no one wants them. so you use them to teach for each other.

Barium and calcium are good mates. Sulfates differentiates between their friendship however, making both become very angry and pale white (ppt). Flouride, being the backstabber it is, reacted with only calcium to form precipiate and not barium.

Copper, is the son of Chopper...you know choppers that fly in the sky? The BLUE sky, ye them. So when you add hydroxide to this little fella, forms blue ppt.
But since the Iron II and Iron III didn't like him flying up in the blue sky, the two tried to steal the hydroxide from him, and starting shooting him from the BROWN earth. Yes both form brown ppt with OH-. When they killed the copper, they got BLOODY with each other. Iron III, the bigger fella, Poisoned (Iron II with) Potassium Permanganate, so he went poor Iron II went all dead and lost life and colour, yes it decolourised the Potassium .... etc But Iron II, although small, but very shifty you know, he took the glass he was poisoned with, broke it and stabbed Iron III, making him produce a deep red BLOODy solution in SCN-.

Well they are all dead.

Lets burn them, should we? Flame tests?

Ba-pple (Barium goes apple green)
Ca-brick (Calcium goes all brick red)
Cu-Blue (Was he besides blue anything else?)


Ahh, nice story ay


In general

1. Add HCL
2. Add H2S04
3. Add NaOH

I love this. I will attempt to remember it.

Hah! That's brilliant!

I just used flow diagrams and memorise those.

Cations are Positive ions mate

Mate you're so wrong... Cations are positive and anions negative

cations are pussytive
