Allergenic plants causing skin eruption by contact include poison ivy (Rhus radicans L.), poison oak (Rhus toxicodendron L.), poison sumac (Rhus vernix L.), and stinging nettle (Urtica dioica L.). In the United States, poison ivy and poison oak cause nearly 2 million cases of skin poisoning and skin irritation annually, for a loss of 333,000 working days. In addition, these weeds cause 3.7 million days of restricted activity among those people who are susceptible to the toxins (1). [Pg.10]

Other living things besides animals also use acid to sting. The stinging nettle bush has sharp, hollow hairs that contain various chemicals, including formic acid, that irritate the skin of any animal that is unfortunate enough to rub up against it. [Pg.90]

Formic acid (HCO2H) is an organic acid secreted by ants and stinging nettles. Calculate the pH and the concentrations of all species present (HCO2H, HCO2-, H3O+,andOH-)in0.20MHCO2H(Ka = 1.8 X 10 4). Also calculate the percent dissociation. [Pg.658]

Methanoic acid is present in stinging nettles and ant stings. Ethanoic acid, however, is the most well known as it is the main constituent of vinegar. Like other acids, ethanoic acid affects indicators and will react with metals such as magnesium. However, whereas the mineral acids such as hydrochloric acid are called strong acids, ethanoic acid is a weak acid (Chapter 8, p. 120). Even though it is a weak acid, it will still react with bases to form salts. For example, the salt sodium ethanoate is formed when ethanoic acid reacts with dilute sodium hydroxide. [Pg.248]
