Question
JUST NUMBER 1 , 3 , AND 5
Circle the questions that have been assigned. 0 Part 4. Describe the chemistry that was occurring in the experiment between the time when solutions A and B were mixed and STOP TIME. 2. Part A.4. For kinetic trial 2, Alicia was distracted when the color change occurred but decided to record the time lapse read from her watch, Will this distraction cause an increase or decrease in the slope of the log (rate) versus log In? Explain. Part A, Table 24.1. a. When doing the kinetic trials, Susan forgot to include the deionized water. Will this omission hasten or delay the formation of the blue color in the trials (exclusive of Trial 6)? Explain. b. When doing the kinetic trials, Oscar mistakenly omitted the sodium thiosulfate solution. How will this omission change the appearance of the resultant solution (from the mixing solutions A and B) from that of a correctly completed experiment? Explain your reasoning. c. When doing the kinetic trials, Peyton mistakenly omitted the starch solution from the kinetic trials. How will this omission change the appearance of the resultant solution (from the mixing solutions A and B) from that of a correctly completed experiment? Explain your reasoning. d. Of the three chemists above, which chemist will have the most accurate results? Explain.Explanation / Answer
What is the solution A and B?
Peyton wouldn't see the change of color. Iodine forms a complex with starch.
Thiosulfate is a reductant. It will reduce iodine to iodide.
