42.8 grams of KIO3 and add H2O until the final homogeneous solution has a volume of 2.00 liters
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.
It contains one potassium ,one iodine and three oxygen atoms per unit.( for ionic compound it is better to use the term 'unit' instead of molecule).
Lugol's iodine, also known as Lugol's solution, first made in 1829, is a solution of elemental iodine and potassium iodide in water, named after the French physician J.G.A. Lugol. Lugol's iodine solution is often used as an antiseptic and disinfectant, for emergency disinfection of drinking water, and as a reagent for starch detection in routine laboratory and medical tests. It is also used for the treatment of goiter.
I have to laugh at you for this question. The chemical formula for KIO3 is KIO3. It's called Potassium Iodate.
Formula: KIO3
Potassium Iodate
KIO3 name is Potassium Iodate
Potassium iodate is composed of a potassium ion, K+, and and iodate ion, IO3-. The formula unit is KIO3.
it is potasium iodate
== Potassium (K) and iodine (I) combine in a one-to-one ratio to form potassium iodide, which has KI as its chemical or molecular formula. A link can be found below for more information.
There is no such compound as KCIO3 However, KClO3 (with a lowercase L) is potassium chlorate.
NaHSO3 + KIO3 => I2 + NaI + K2SO4 + H2O
