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.
Dysbiosis in the mouth is also very common and results in tooth decay and poor periodontal health (4). The majority of microbes live in the gastrointestinal tract, and more specifically in the large intestine where they digest some of the food we eat and regulate our immune system and intestinal barrier function.
