Complications. 1  Water insoluble compounds should be dissolved in ethanol, methanol, or acetone. 2  Often, the brown precipitate fails to form and the solution turns reddish-brown. 3  Easily oxidized compounds give a positive test: a) Most aldehydes give a positive test. 4  Alcohols with trace impurities give a positive test.
Palmetto Trail. The Palmetto Trail is a planned 425-mile-long (684 km) foot and mountain bike trail in South Carolina for recreational hiking and biking. Several of the sections are also equestrian trails. It will extend from the Oconee County mountains to the Intracoastal Waterway in Charleston County.
âThe problem with an unapproved, generic common name like palmetto bug is that different people will use it to name different species of cockroaches,â Benson says. âFor some in South Carolina, a palmetto bug is an American cockroach. For others, especially along the coast, a palmetto bug is a smokybrown cockroach. In Florida, many people call Eurycotis floridana, the Florida woods cockroach (the approved common name), the palmetto bug.â So if you think a palmetto bug is a reddish brown cockroach 1 to 2 inches in length, thatâs probably an American cockroach. If you think itâs a cockroach of a cooler brown hue, up to 1 Â½ inches in length, that might be a smokybrown cockroach.
