In this experiment, 4.65 mL drippings (from H
2 flame on
ice cube) were collected and then (left) 0.25 mL, (middle) 0.50 mL and
(right) 1.07 mL of 0.00082 M KMnO
4(aq) were added to the
drippings (left picture) and to a similar amount of distilled water
(right picture). The yellow color is due to manganese(IV)
oxide/hydroxide which did not precipitate due to the dilute
concentration, 0.00016 M.
