2KI(aq)+(NH)SO(aq)2K(SO)(aq)+SO(NH)(aq)+2I(aq)What is/are the spectator ion(s)?K, I, NH, SOIs this reaction fast or slow?FastNaSOKIKNO(aq)+NHSON2SO(aq)What is/are the spectator ion(s)?Is this reaction fast or slow? FastWhat reagent is added that will change color? What is it reacting with? What color will it turn?The reagent added that makes it change color is starch. The starch combines with the 2I, turning it a dark purple.Which reactant must be used up before the indicator changes color?The2-main reagents (the I- or the S2O8) to discover the effect of the concentration on rate.Which of the main reagents was in the beaker? Which of the main reagents was in the test tube? Which reagent was added to keep a constant volume and constant concentration of K+? Which reagent was added to keep a constant volume and constant concentration of NH4+? What was the TOTAL volume (in drops) used for each run (beaker + test tube)? 1-48 drops 4-48 drops2-48 drops 5-48 drops3-58 drops Did you modify any of the volumes or accidentally add more drops of one or more reagents during your multiple trials? If so, describe any differences to your procedural steps. (The changes in volume must be accounted for in your calculations!)2-concentration (in M) of I- and S2O8Run #:? (Show your work and indicate which runs data you are using)Run #:[I-]1:[S2O8]1:V1 (in drops): V2 (in drops):V1 (in drops):V2 (in drops):2-[I-]2 =[S2O8] =Upon the instant the solutions are mixed, what is the concentration (in M) of thiosulfate for all of the trials? (Show your work)Which reactants concentration can you calculate an exact change over a given time? Write the equation for calculating the initial rates of each of these reactions. The indicator changed color when all the thiosulfate ions, S2O32-, were used up. Upon the instant the2-solutions were mixed, you calculated a molarity of S2O3(from Q 9). Since the concentration of2-thiosulfate changed from this value to zero this is the value of D[S2O3point of the color change for each of the runs? (Show your work)]. What is the value of D[I2] at thePick one run from your data set in Table 2 and calculate the initial rate for that reaction using this value of I2 concentration and the average time. Show your work and indicate which runs data you are using.BELOW.
