Example: Calculate the pH of a buffer solution that initially consists of 0.0400 moles of ammonia and 0.0250 moles of ammonium ion, after 20.0 mL of 0.75 M NaOH has been added to the buffer. Ka for ammonium ion is 5.6 x 10 -10.
There are two types of bacteria. Aerobic bacteria live with oxygen, love the company of food particles in the mouth and feed on sugar. Anaerobic bacteria exist without oxygen and feed off dead skin cells and other bacteria.
Bacteroides are some of the most common anaerobic bacteria species in the foot wounds of diabetics. Often, anaerobes co-exist with aerobic bacteria, which need oxygen to thrive. This is common in foot ulcers, which makes them more difficult to treat. Other anaerobes, such as those in the Actinomyces genus, can cause dental infections within the mouth.
