Why is Maintaining pH important?

Answer 1

It depends on what system you're talking about. For instance, in our bodies, it is important to maintain a relatively consistent pH because if our blood was more or less acidic this could denature enzymes that help us maintain our homeostasis rendering us dead.
Almost if not all metabolic and biochemical processes in nature simply work best at a certain pH range and so biological buffers are used to keep the pH around + or - 1 of where the pH is supposed to be.
If our stomach didn't remain at a low pH, we couldn't make pepsin from pepsinogen and digestion couldn't occur as efficiently if at all.
Certain chemical experiments rely on consistent pH so the reactions can proceed.

There are all kinds of reasons why maintaining pH is vital to some processes and biologically speaking, its vital to life itself.
My answer is probably an oversimplification, but the question isn't very specific. If you look in your biology or chemistry books about buffers, I think you'll find the discussion informative.

I hope that helped some.

Answer 2

Controlling pH in the body is important, because the body likes to stay around neutral (SLIGHTLY basic if anything) in order to maintain homeostasis. The body can function best at neutral pH. If the pH is too acidic, enzymes can start to denature and stop functioning. Same goes for too basic.

Answer 3

Maintaining pH is important, because either ends of the scale are dangerous.. if things get to acidic, they become corrosive..the same holds true base materials.. two examples are lye-base and hydrochloric acid-acid.. either is harmful to you.
In a swimming pool, controlling pH is important because it keeps the salts in the water from calcifying within the sand in the filter. a high level pH and the chlorine does not work effectively..too low and the filter is at risk of seizing.. this takes a long time, but the sand will eventually clump together and calcify.

Answer 4

Homeostasis = Maintaining core body conditions, like temperature, water level, blood pH. Kidneys filter the blood controlling pH value.

Answer 5

The ideal blood pH is slightly alkaline, with a normal range of 7.35 to 7.45. Anything above that is alkaline, and anything below is considered acidic, both result in symptoms of disease. If the pH moves below 6.8 or above 7.8, the cells of the body stop functioning and the human will die.
