I try to remember the positive and negative by Anion sounding like onion and onions make my cri so they're negative

I remembered it as cation = cat so positive, cathode like chode so negative

I learn it as cathode - cat - pussy

YOU MADE ME UNDERSTAND ELECTROLYSIS!! THANK YOU!!

[@jameskilleen4083]

I was so confused about which element forms at the cathode and anode before I saw your video. Insanely helpful!

[@hiddens0ck289]

Great video didn’t understand it in class but now I know it like a pro. Thanks

My students will enjoy the class this morning. Thank you very much for posting this wonderful video. The understanding is clear.

this is quality, thank you so much

[@sanaadawood1526]

there is literally no need of me going to chemistry lessons bcz of ur videos!

[@dewsjievpdav6557]

I think it’s important to note that if the salt is in a solution, and the negative ions in the ionic compound aren’t halide (group 7), then the hydroxide ions are oxidised, which produces water and oxygen. Only if the negative ion is a halogen then it will be oxidised.

[@lichh64]

It needs to be a concentrated solution for the halide ion to get oxidised otherwise it will be the hydroxide ion.

[@sidharthsubramanian1283]

thank you so much man

How about placing this ionic solutions in between two inducting coils instead of direct current connections.

Are both examples ionic bonding

"What do you know about lead bromide?" Sounds like you probably shouldn't inhale it

Wait I don’t understand, why does the water disassociate during the electrolysis of salt?

Panic_postitve Anode,negative is Cathode

[@daniinolte5486]

So we can use molten NaCl or we can dissolve NaCl in water?

[@edwardhaigh8298]

think you would dissolve it because of its very high melting point, but it would work as either molten or dissolved

[@hlomphoprincess3573]

love these vids but my periodic table has lead in group four why are they different?

[@ezjohnny]

must be printing mistake

[@aidenwinter1117]

Wooow new video woohoo

[@mewa3438]

How do you know the lead ions are positive and bromide ions negative?

[@freyah4213]

Humera Iqbal by looking at their group in the periodic table

[@zahrashafiq4280]

metals are positive, bromine is a halogen (group 7 so negative)

[@BossBoss-wx6mx]

Can anyone explain why the lead bromide changes to Pb2+ and Br- please?

[@Saucerer6]

it doesn't change, the lead bromide is molten, so it's been melted somewhat. All that does is dissociate the lead and bromide from their compound lead bromide and allows them to move around.

[@naominewman710]

Pb (lead) forms 2+ ions
Br (bromine) forms 1- ions
so for a neutral ionic bond we have PbBr2 , when separated we get 1 Pb2+ and 2 Br- ions
it is seperate because in an ionic bond the ions already exist in a lattice, usually unable to conduct or flow due to strong electrostatic intermolecular attraction but the heat from being made molten breaks the lattice and leaves the ions more or less flowing freely

[@ok-ij5nn]

do i need to know this for combined?

[@Muslim_26]

What do you do when you can't remember the charge of the anode or cathode?
PANIC(Positive Anode Negative Is Cathode).

[@evie.taylorcokayne9687]

Remember PANIC. Positive Anode Negative Is Cathode
