Find the concentrations of [IO3] and [HSO3] and enter into the table. Divide the
concentration of HSO3 with the time in seconds to get the rate.
Volume is assumed to be additive in this experiment. Thus, the total volume of all the
solutins is assumed to be 20.0 mL. This introduces a small error that can be considered
insignicant. The concentrations of IO; and HSO, (after mixing but before the reaction
begins) can be calculated using the relationship: Mailute Vdilute= Mcone Vcone. A sample
calculation is shown below for the concentration of IO, in Trial 1:
