redox
oxidation
definition
increase in oxygen
decrease in hydrogen
increase in oxidation state
decrease in electrons
itself will be reduced
ACIDIFIED potassium manganate (VII)

MnO4^[-] + 8H^[+] + 5e^[-] —> Mn2^[+] + 4H2O
purple to colourless
ACIDIFIED potassium dichromate (VI)
gain electrons
Cr2O7^[2-] + 14H[+] + 6e- —> 2Cr[3+] + 7H2O
orange to green
reduction
definition
decrease in oxygen
increase in hydrogen
decrease in oxidation state
increase in electrons
itself is oxidised
KI is a common reducing agent
lose electrons
from 2I- to I2
turns yellowish brown (bio solution)
oxidation state
charge
if its a covalent molecule, the o.s. is 0
in ionic compounds, oxidation state is 0
