How to determine the inital molar concentration of hio3

Reference no: EM13285185

A 1.0 mL volume of 0.010 M H2SO3 is added to a mixture of 12 drops of 0.010 M HIO3, 8 drops of deionized water, and 1 drop of starch solution. A color change in the reaction mixture occured after 40 seconds. A. Assuming 25 drops per mililiter for all solutions, determine the inital molar concentration of HIO3, after mixing but before any reaction occurs (at time=0). Units are molHIO3/total volume (L). B. The rate of the reaction is measured by the disappearance of HIO3. For the reaction mixture in this question, what is the reaction rate? Express the reaction rate in units of molHIO3/L/sec to the correct number of significant figures.
