42.8 grams of KIO3 and add H2O until the final homogeneous solution has a volume of 2.00 liters
Titrate it with a primary standard
A solution that has been titrated against a primary standard solution.
Standardization of sodium thiosulfate uses potassium iodate with excess potassium iodide and acidified. Iodine is liberated and that is titrated with sodium thiosulfate. KIO3 + 5KI + 3H2SO4 -----> 3K2SO4 + 3H2O + 3 I2 I2 + 2Na2S2O3 -------> 2NaI + Na2S4O6 So 1 mole of KIO3 produces 3 moles of Iodine. 1 moles of iodine reacts with 2 moles of thiosulfate. So 6 moles of sodium thiosulfate react with 1 mole of potassium iodate KIO3.
i need ideas to complete my assignment
what is the advantage of potassium iodate as aprimary standard
what is the advantage of potassium iodate as aprimary standard
KIO3 name is Potassium Iodate
I have to laugh at you for this question. The chemical formula for KIO3 is KIO3. It's called Potassium Iodate.
it is potasium iodate
Formula: KIO3
Potassium Iodate
we use primary standard apparatus in chemistry lab to find accurate resultthe examples of primary standard apparatus arepippetteburreteVolumetric Flask
There is no such compound as KCIO3 However, KClO3 (with a lowercase L) is potassium chlorate.
HCl is not used as a primary standard
It is primary standard is a substance that has a known high digree of purity ,reatively large molar mass ,is nonhygroscopic and reacts in a predic table way.
NaHSO3 + KIO3 => I2 + NaI + K2SO4 + H2O
