A quick roadside grab on a quiet country road, one of the 60 caches in the Bones'n'Booth (shortened to B.B.) Series. They are designed to be a variety of puzzles, multis, traditionals and letterbox hybrids of varying size, terrain and difficulty.
Phenolphthalein is a chemical compound with the formula C20H14O4. Often used in titrations, it turns colorless in acidic solutions and pink in basic solutions. If the concentration of indicator is particularly strong, it can appear purple. In strongly basic solutions, phenolphthalein's pink color undergoes a rather slow fading reaction and becomes colorless again.
Phenolphthalein is insoluble in water and is usually dissolved in alcohols for use in experiments. It is itself a weak acid, which can lose H+ ions in solution. The phenolphthalein molecule is colorless. However, the phenolphthalein ion is pink. When a base is added to the phenolphthalein, the molecule ⇌ ions equilibrium shifts to the right, leading to more ionization as H+ ions are removed.
Phenolphthalein is used in a test to identify substances that are thought to be, or to contain, blood. This test is commonly known as the Kastle-Meyer test. A dry sample is collected with a swab or filter paper. First a few drops of alcohol, then a few drops of phenolphthalein and finally a few drops of hydrogen peroxide are dripped onto the sample. If the sample contains hemoglobin, it will turn pink. This is considered a positive test and indicates that the sample contains hemoglobin and, therefore, is likely blood. This test is nondestructive to the sample; it can be kept and used in further tests at the lab. This test has the same reaction with blood from any animal, so further testing would be required to determine whether it originates from a human.
The cache is designed to be an easy grab, please take care to return it as found. It`s an easy grab and shouldn`t take more than a few moments to grab.
Please enjoy and return as found. Also, BYOP to sign the log.
