I need to convert from 0.1 N potassium Iodate to molarity.

Question

I need to convert from 0.1 N potassium Iodate to molarity.

Answer 1

Potassium iodate has a chemical formula:

KIO3

It has 1 replaceable iodate (factor).

then,

Molarity = Normality / factor

            = 0.1 N / 1 = 0.1 Molar

Answer 2

it depends,

if you are using it as a salt to make precipitates with the iodate, bernie is right

=================

if however you are using it as an oxidizer, say in a redox titratration, or in an iodine clock rate reaction, it is quite different.  For normality reflect the power of the molecule (equivalents), as well as the moles of molecules per litre .  often normalities are multiples of the molarity, because of what the molecule can do:

1 mole of (IO3)-1 ....takes 5 moles of electrons when it acts as an oxidizer forming I2

therefor its normality as an oxidizer is 5 times is Molarity

your answers:

0.1 Normal KIO3  equals 0.1  Molar KIO3 (as a salt)

0.1 Normal KIO3 equals 0.02 Molar KIO3 (as an oxidizer)
