The equation between potassium iodate (KIO3) and sodium thiosulfate (Na2S2O3) involves a redox reaction. In the presence of an acid, potassium iodate is reduced to iodine (I2), while sodium thiosulfate is oxidized to form sodium tetrathionate (Na2S4O6). The balanced chemical equation for this reaction is 5Na2S2O3 + 2KIO3 + 8HCl → 5Na2S4O6 + 2I2 + 2KCl + 6H2O.
What else can I help you with?
Why do you use starch to standardise sodium thiosulphate using potassium iodate?
Starch acts as an indicator for the endpoint of the reaction between sodium thiosulphate and potassium iodate, as it forms a blue-black complex with iodine. This color change helps identify when all the iodine has been liberated from the reaction. This method is commonly used in titrations to determine the concentration of the sodium thiosulphate solution accurately.
What is the equation for potassium iodate with acidified potassium iodide?
The reaction between potassium iodate and acidified potassium iodide can be represented by the equation: $$ \text{IO}_3^- + 5\text{I}^- + 6\text{H}^+ \rightarrow 3\text{I}_2 + 3\text{H}_2\text{O} $$ Here, potassium iodate is reduced to iodine while oxidizing iodide ions to iodine.
What is the mole ratio between the iodate and thiosulphate ions?
The mole ratio between iodate (IO₃^-) and thiosulfate (S₂O₃²-) ions is 1:3 in the reaction between the two ions, as seen in the balanced chemical equation of the reaction. 2S₂O₃²- + IO₃^- → S₄O₆²- + I⁻
Is potassium Iodide similar with potassium iodate?
Potassium iodide (KI) and potassium iodate (KIO3) are related compounds that both contain iodine and potassium. However, they have different chemical structures and properties. Potassium iodide is commonly used as a nutritional supplement to prevent iodine deficiency, while potassium iodate is used in some countries to fortify table salt with iodine.
A chemist dissolves 3.50 g of potassium iodate and 6.23 g of potassium hydroxide in 805.05 g of water what is the percentage concentration of each solute in the solution?
The specified amounts of materials add to 814.78 grams total. Therefore, the percentage concentration by mass of potassium iodate is 100(3.05/814.78) or 0.374 percent, to the justified number of significant digits, and the percentage concentration by mass of potassium hydroxide is 100(6.23/814.78) or 0.765 percent, to the justified number of significant digits.
How do you calculate number of moles of iodine liberated bsed on thisEquation between potassium iodate and sodium thiosulphate?
To calculate the number of moles of iodine liberated in the reaction between potassium iodate (KIO₃) and sodium thiosulfate (Na₂S₂O₃), you first need to write the balanced chemical equation for the reaction. Typically, potassium iodate reacts with sodium thiosulfate to produce iodine (I₂) and other products. By determining the stoichiometry of the balanced equation, you can use the moles of the reactants (KIO₃ and Na₂S₂O₃) to find the corresponding moles of iodine produced, applying the mole ratio from the balanced equation.
How do you calculate the molarity of potassium iodate in redox titration?
To calculate the molarity of potassium iodate in a redox titration, you can use the balanced chemical equation for the reaction between potassium iodate and the reducing agent. By knowing the volume of the reducing agent used in the titration and the molarity of the reducing agent, you can determine the molarity of the potassium iodate. The equation should be balanced in terms of moles of the substances involved.
