electrolysis Flashcards
what is the flow of electrons in the electrodes
anode to cathode
OIL RIG
oxidation is loss , reduction is gain
name the equipment used in electrolysis
1.beaker
2. electrolye
3. elecctrodes
4. a wire
5. a battery
what is electrolyte
a substance that contains ionic compounds
can electrolyte be soluble or insouble
it can be both
what do you do if the electrolyte is insoluble
melt into molten liquid
why do you have to melt the electrolyte into molten liquid if it is insolunle
so ions can move freely in liquids
what do you do if the electrolye is soluble
dissolve it in water
how many electrodes are there
2
what are the names of the electrodes
anode(positive) cathode (negative)
PANIC
positive anode, negative is cathode
what are the electroddes made out of
inert carbon or metal
what does inert measn
doesn’t take place in the reaction/ unreactive
what does the wire do
attaches to two electrodes, transports the flow of electrons
what does the battery do
drive the flow of electrons
what happens at the cathode during electrolysis
cations(positive ions) will be discharged to form a neutral particle
what happens at the anode
anions(negative ions) willl ne discharged to form a neural particle
what is a postivey charged ion
cation
what is a negatively charged ion
anion
what is electrolysis
sepearating iojnic compounds into their pure element by passing electric current through electrolyte
what does an electric current sent by the battery do
sepearrate the iwo compounds
what do the electrodes do
conduct electrons as they pass through
how many ways are there to extract metals from their oress
- reduction with carbon
- electrolysis
when is reduction by carbon only used
if the metals are below carbon in the reactivity series
