Hey,

Could anyone explain to me the following:
Why is 1N Na2S2O3*5H2O equal to 1M Na2S2O3*5H2O? Could you explain the process of conversion.
Why is 1N Iodine equal to 0.5M Iodine? Could you explain the process of conversion.

What to know:
Molar mass of Na2S2O3*5H2O = 248.18g/mol
Molar mass of I2 = 253.80g/mol
N - normality
M - molarity (molar concentration)

Try to write reaction equations (half reaction equations to be precise).

See how many electrons are exchanged per S₂O₃^2- and per I₂.
