How Does Hydrochloric Acid Affect The Rate Of Iodate Reaction
If the concentration of the reactant (Potassium Iodate) decreases, then the rate of reaction with the other solution (Sodium Bisulfite) in the mixture will be slower, and the time taken to form a compound between the two solutions will be longer. When an Iodate ion takes up space in between the gaps in the structure of the amylose, it causes a reaction, where negative polyiodide ions are formed. Thus, the time taken for the the Potassium Iodate ions to reach a fixed threshold of moles produced to react with the amylose found in Sodium Bisulfate will take longer, as there are less iodate ions to occupy space in between the helix structures of Amylose that is found in Sodium Bisulfate. Iodate is a powerful oxidizing agent; it will oxidize the

    During this experiment, acids of different concentration are utilized, and the different reaction rates calculated. When the reactant’s concentration increases, there are more atoms per space for a collision to occur. A prediction for the effect of concentration on reaction rate would be that the higher the concentration of the reaction, the faster the reaction time. As the temperature of the reaction rate increases, the molecules will move faster, also resulting in more collisions and perhaps a faster reaction rate.…

    The rate of a chemical reaction often depends on reactant concentrations, temperature, and if there’s presence of a catalyst. The rate of reaction for this experiment can be determined by analyzing the amount of iodine (I2) formed. Two chemical reactions are useful to determining the amount of iodine is produced.…

    This experiment was run so that the students could learn to find the formula of ionic solids formed in reactions and to write the chemical equation that corresponds to it. In order to do this, students must first run qualitative tests for the ions in the solution. While testing for anions, iodide and nitrate react with H2O2. Iodide formed separate layers and nitrate had no observable change. While testing for cations, lead and potassium reacted with H2S. Lead turned grey then a dark precipitate settled at the bottom. Potassium remains clear even after heating. Next, lead nitrate was added to potassium iodide. During the test for anions (again with H2O2), the solution turned purple. This signifies the presence of iodine. During the test for cations (again with H2S), the solution turned grey and a grey precipitate formed after heating. This signifies the presence of lead. Lastly, numerous tests were run to determine the exact ratio of ions in the precipitate. Lead nitrate and potassium iodide were…

    The purpose of laboratory assignment 3 was to measure the rate at which a chemical reaction takes place. For the purpose of this lab we measured the rate a balanced oxidation/reduction reaction between iodine, hydrogen, and bromate ion occurs. The above reaction occurs slowly so we used a coupled iodine clock reaction to measure the rate of the oxidation/reduction reaction because it occurs much faster but is still dependent upon the other reaction. To accomplish this, two mixtures were prepared in separate Erlenmeyer flasks. In the 250 ml flask .010M potassium iodide, .0010M Sodium thiosulfate and distilled water was prepared. A 125 ml flask was also prepared with a mixture of .040M potassium bromate, hydro chloric acid and…

    Reaction (4) is an iodine-starch reaction, used solely to determine when the production of iodine is occurring by turning a clear colorless solution to a blue color. Without reaction (4) it would be very difficult to determine how much iodine is being produced, due to how rapidly thiosulfate and iodine react. However reaction (4) does not determine the amount of iodine produced, it only determines when iodine is present in solution. Essentially reaction (3) is used to determine how much iodine is produced.…

    The Iodine Clock Reaction

    • 824 Words
    • 4 Pages

    2 S2O32−(aq) + I2(aq) → S4O62−(aq) + 2 I−(aq) This reaction is much faster than the previous, so the conversion of I2 back to I− is essentially instantaneous. In a typical experiment, known concentrations of S2O82- and I− are mixed with a small amount of S2O32- and starch. As reaction the first proceeds, S2O82- and I− react to produce I2, but nothing appears to be happening because the second reaction is consuming the I2 as quickly as it is formed. The important moment is when the S2O32- runs out, for then the I2 is no longer consumed (see the second reaction), and the dark blue starch−I2 complex forms. The stoichiometry of the second reaction indicates that one I2 molecule must have been generated for every 2 ions of S2O32 − initially present in the solution. [I2 ] generated(from first reaction) = [I2 ] consumed(in second reaction) = {1/2[S2O32-] initially present} Note that the change in concentration of I2 (before the blue complex forms) is fixed by amount of S2O32- included in the initial reaction mixture. 1 [ S O2 − ] d [ I2 ] 2 2 3 rate = = dt t Where t = time for blue color to appear. In this experiment you will: A. Determine Rate Law and Rate Constant {k is constant at constant temperature} B. Vary temperature and estimate EA {Using the Arrhenius Equation} A.
