Logo of Bear Springs Blossom Nature Conservation, international charitable nonprofit organization providing nature conservation education to all countries on Earth Signature of Bear Springs Blossom Nature Conservation, international charitable nonprofit organization BSB Environmental conservation education online: Maps of America. Bear Springs Blossom Nature Education + Conservation, protection of air, for all life, flora + fauna on Earth = human protection, because humans need healthy air. Science based Nature education about water + air on Earth = human protection, education of  soil on Earth = human protection. Learn online about nature conservation, how to update your knowledge, how to understand weather, floods, earthquakes and storms. Biology teaches that life on earth depends on plants, that produce oxygen, provide food. BSB Environmental conservation education online: Bear Springs Blossom Nature Conservation BSB offers science based nature education with Earth maps, BSB maps of the America, environmental education with an Earth pollution map, earth rainforest map, United States map, South America map, Central America map. Humans need Nature education to stay healthy, protected from chemical pollution. To understand Earth's natural environment we need to learn and study. earth is our only home, the blue planet we need to survive - Nature education on air. Get science based facts. BSB has to report bad behavior, destruction of nature, polluting air, soil and water, all the time. News on Ocean conservation + Water conservation is needed for protection of all life, flora + fauna on Earth. News on environmental changes in oceans worldwide hint to the coming changes for humans. Nature conservation news tells you about Earth' environment. Environmental news to protect air + water + soil + food. BSB-research published in these news helps to keep Nature beautiful + to secure our future to give people a better life!

Water education online: man made chemicals change water alkalinity, ph, lye can be dangerous to children and adults
About pH values

Did you hear about different pH values?
Every cook has to deal with pH levels?
What makes pH levels so different?
Comparing pH of orange juice with milk:
Is there a difference?
The danish Chemist Soren Sorensen created this term in 1909
p = latin potentia = pressure
H = Hydrogen
Pure water has a pH of 7 = pH 7 is seen as neutral. Where do you think are pH measurements used? pH is important in medicine, biology, chemistry, food science, environmental science, oceanography, civil engineering and many other applications
Water science: water can be acid or alkaline, the pH level can be very different. Water chemistry pH scale with 7 as neutral

Pure water has a pH of 7 = pH 7 is seen as neutral.
Solutions with a pH less than 7 are called acidic
solutions with a pH greater than 7 are called basic or alkaline.

The pH scale is logarithmic, so every one-unit change in pH actually represents a ten-fold change in acidity. This means that pH 6.0 is ten times more acidic than pH 7.0, and pH 5.0 is 100 times more acidic than pH 7.0
A range of pH 6.5 to pH 8.2 is optimal for most organisms

Human blood stays in a very narrow pH range right ~ 7.35 - 7.45. If your body pH does not fit in this range you are not healthy, you have some kind of disease.
If blood pH moves to much below 6.8 your cells will not work anymore, you will die.
The same happens when you body pH goes above 7.8
The ideal pH for blood is 7.4
A healthy blood pH without cancer has acid + alkaline balance almost equal.
Look at the graphic:

pH levels in our body should be balanced. Graphic shows the very different pH levels in the human body. So you see pH measurements are important in medicine, biology, chemistry, food science, environmental science, oceanography, civil engineering and many other applications
If you have a health problem, most likely you are acidic. Research shows that unless the body's pH level is slightly alkaline, the body cannot heal itself. Part of taking care of our body and to deal with health problems is to balance our pH values. You cannot become healthy until the pH level is in the right range. An unbalanced body cannot effectively assimilate vitamins, minerals and food supplements. Your body pH affects everything.
Lets have a Quiz about pH levels
What do you think?
What pH level has beer?


Most beer have a pH level of 4.6

What do you think?
What pH level has soap?


Most soaps have a pH level of 9.5

What do you think?
What pH level has bleach?


Bleach has a pH level of 12.5

What do you think?
What pH level has vinegar?


Most vinegar have a pH level of 2.5

What do you think?
What pH level has orange juice?


Orange juice has a pH level of 3.6

the ph level of the skin is important. Too much soap can endanger the skin, changing the ph level
