Water Clear
Again and again the experiment changes the color of clear water You know?

They remember that I started to experiment Scientific view of the clear liquid was water in them. The solution they Became darker and darker to black liquid with a different "water" of Added a small amount. And they are of different solutions and liquid Add a small amount was again clear, perhaps. But I was impressed Heat or temperature changes. For a second grade classroom to anyone Similar demonstrations can I know? Although most of Science_Guy_88 I do not get good answers, and a link to a good video Given, I'm not looking. Room temperature before mixing in a I'm looking for liquid times. Start a clear liquid, and each of the main In addition, to get dark. Then add the last of the main liquid Obviously again. I'm not a chemist, you can not buy Things could not be accessed from the hobby shop.

Briggs - Rauscher reaction. For the initial solution, iodate, author of the manganese (Mn2 +) as catalyst Strong chemicals, including hydrogen peroxide and unreactive acid (sulfuric acid (H2SO4), or perchloric acid (HClO4) good), and activated carbon in organic compounds with Connected ("enolic") which hydrogen atoms slowly (I ...) iodide Free iodine (I2) is reduced. (Malonic acid (CH2 a (COOH) 2) Is excellent for that purpose.) Sudden increase in starch choice Additional indicators are shown in blue) and dark amber iodine (Free from sudden changes in concentration of iodine ions in Is required for both iodine and iodide. "" Iodine - Starch composite) Notes (: reaction thus should be avoided chloride (damn CIA) ions by the "addiction" is. Initial concentration of the reaction is very The following is a wide range of shimmer. This is referred to as the fluctuation Once known as a mixed reaction, with the dark Blue Color of pumpkin Changed back to its more than pumpkins back to cancel. It is truly impressive four second graders will be.

Then, this solution certainly can not go back to Reducing agent is added. To accomplish this task most The easiest way is to add a cheap and easy Internet Order sodium Borohydride (NaBH4) solution. You alkali Or alkaline earth metals that the behavior of one or more of I just can not be added to starch iodine complex Magnesium is the solution.
