electrochemical reactions rely on redox reactions

 

spontaneous reactions are exothermic

potential difference between electrodes change with temperature and concentration

inert electrodes like carbon or platinum are used as they don't react with the electrolytes or the products of the reaction

when a salt melts the ions are free to move (and so can carry current and can acts as an electrolyte)

but then as the reaction continues the electrolyte is decomposed

in a salt solution metals more reactive than hydrogen will reduce (ie. above hydrogen)

 

halides will oxidise, otherwise  its OH minus ions

 

relevant to maths right now

science just done, bio was done with this morning

so all set with that

Oh integration by parts

ah, Science, bio, back to back tests

So much calculus

glad the IT test didn't change to tomorrow, that would be three in a row

Sneaky initial conditions, hiding away in the corner there *narrows eyes*
