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.
There are many types of bacteria in your mouth that normally control the growth of Candida. Sometimes a new type of bacteria gets into your mouth and disrupts the balance of the organisms already there, allowing Candida to overgrow. Health conditions and other things may also be involved.
