How many moles of iodine are liberated
Web6 apr. 2024 · Explanation: Dissolve 9.31 g of N a2S2O3 ⋅ 5H 2O into 250mL water. Molarity is moles/Liter. 0.150 M in 250mL is ¼ of 0.150 moles/L, or 0.0375 moles/0.25L. N a2S2O3 ⋅ 5H 2O just has the extra mass (moles) of water to consider. That is irrelevant to this problem because we are already given the molar mass for the compound. http://mccscience.yolasite.com/resources/EXP%204.7.pdf

Web12 mrt. 2024 · So, only 1.67*10^-2 moles of sodium iodide will react fully until there is no more of it. The mole ratio between NaI and NaCl is 2:2=1, so if 1.67*10^-2 \ "mol of" \ NaI are used, then also 1.67*10^-2 \ "mol of" \ NaCl are created. Now, the question asks to find us the mass produced, ... WebIn many cases the liberated iodine is titrated in the mildly acidic solution employed for the reaction of a strong oxidizing agent and iodide ion. In these cases the titration of the liberated iodine must be completed quickly in order to eliminate undue exposure to the atmosphere since an acid medium constitutes an optimum condition for atmospheric …
Web23 sep. 2024 · First, we must examine the reaction stoichiometry. In this reaction, one mole of AgNO 3 reacts with one mole of NaCl to give one mole of AgCl. Because our ratios are one, we don’t need to include them in the equation. Next, we need to calculate the number of moles of each reactant: 0.123 L × ( 1.00 m o l e 1.00 L) = 0.123 m o l e s N a C l.
