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 occured after 40 seconds.

assuming 25 drops per mL for all solutions, determine the initial molar concentration of HIO3 after the mixing but before any reaction occurs (at time 0)
