Question

state the purpose for each of the following solutions

a. deionized water

b. buffer solution

3.) In the kinetic analysis of this experiment for the reaction of iodide ion with hydrogen peroxide, state the for the reaction of iodide ion with hydrogen peroxide, state the purpose for each of the following solutions (see Table 24.1): a deionized water buffer solution (acetic acid, sodium acetate mixture) Arthenius Plot for at Chemical Reaction 3.10 3.20 3.30 3.40 -5.50 -6.00 -6.50 ?-8.00 -8.50 -9.00 -10 /T(K) x 1 Experiment 24 287 165

Explanation / Answer

a. Deionized water is used as the solvent. It is deionized so that unnecessary ions do not interfere with the reaction between iodine and hydrogen peroxide.

b. The buffer is added to keep the ph of the solution steady at mildly acidic range (pH 4-6).
