What is the concentration of a potassium iodate solution after you complete the following porcedure? pipette 10 ml of a 0.31 m potassium iodate stock solution to a 100-ml volumetric flask and then add water to the mark.

Given:

Initial concentration of potassium iodate (KIO3) M1 = 0.31 M

Initial volume of KIO3 (stock solution) V1 = 10 ml

Final volume of KIO3 V2 = 100 ml

To determine:

The final concentration of KIO3 i.e. M2

Explanation:

Use the relation-

M1V1 = M2V2

M2 = M1V1/V2 = 0.31 M * 10 ml/100 ml = 0.031 M

Ans: The concentration of KIO3 after dilution is 0.031 M

c is the answer because when something is left after something evaporates that shows the chemical change.
