"Mud" + "Blood"--A Very Colorful Demonstration.
Hambly, Gordon
Journal of Chemical Education, v75 n1 p56-57 Jan 1998
Describes a demonstration in which a bloodred-colored solution of hydrogen peroxide, sodium hydroxide, and phenolphthalein indicator is added to a mud-colored solution of potassium permanganate, hydrated manganous chloride, and sulfuric acid. The mixture turns clear when added together. Draws parallels between the demonstration and the Old Testament beliefs of sin and blood. (DKM)
