10-ml volume of 010 m h2so3 is added to amixture of 12, Ask an Expert

Academics

1.0-mL volume of .010 M H2SO3 is added to amixture of 12 drps of .01 M HIO3, 8 drops of deionized water, and 1drop of starch solution.A color change in the reaction mixtureoccurred in 40 seconds.

a. Assuming 25 drops per milliliter, determine the initialmolar concentration of IO3- after the mixing but before anyreaction occurs (at time=0)?

b. At the same point in time (see part a, time= 0), what is the molar concentration of H2SO3?c. The rate of the reaction is measured by the disappearance of H2SO3. For the reation mixture in this question, what is thereation rate? Express the reaction rate with appropriateunits?
