What is the full meaning of pH?
potential of hydrogen
The letters pH stand for
potential of hydrogen, since pH is effectively a measure of the concentration of hydrogen ions (that is, protons) in a substance. The pH scale was devised in 1923 by Danish biochemist Søren Peter Lauritz Sørensen (1868-1969).
What does pH mean in the body?
The pH scale measures how acidic or alkaline — basic — something is. Your body works constantly to carefully control pH levels of blood and other fluids. The body's pH balance is also called the
acid-base or acid-alkaline balance. The right pH levels are needed for good health. The pH scale ranges from 0 to 14.
Why do we say pH?
The term "pH" was first described by Danish biochemist Søren Peter Lauritz Sørensen in 1909. pH is
an abbreviation for "power of hydrogen" where "p" is short for the German word for power, potenz and H is the element symbol for hydrogen. The H is capitalized because it is standard to capitalize element symbols.
What do the letters pH literally mean?
What do the letters "pH" literally mean?
potential hydrogen.
What is the pH of blood?
Blood is normally slightly basic, with a normal pH range of
about 7.35 to 7.45. Usually the body maintains the pH of blood close to 7.40. A doctor evaluates a person's acid-base balance by measuring the pH and levels of carbon dioxide (an acid) and bicarbonate (a base) in the blood.
How is pH calculated?
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression:
pH = - log [H3O+]. ... On a calculator, calculate 10-8.34, or "inverse" log ( - 8.34).
What pH level is harmful to humans?
A blood pH level that falls
below pH 7.35 indicates a severe problem with lung or kidney function. This condition, termed acidosis, causes a buildup of acid in the tissues and fluids and can be fatal if left untreated.
What pH should your body be?
Human life requires a tightly controlled pH level in the serum of
about 7.4 (a slightly alkaline range of 7.35 to 7.45) to survive [1].
Why P in pH is small?
pH is an old abbreviation for a french description of the acidity of water. The French term is "puissance d'hydrogen", which means "power or strength of Hydrogen". The p is
small because it refers to a word.
What is a pH of 0?
A solution that has a pH of 0 is
very acidic with a high concentration of hydrogen ions (although things can be of greater acidity), a pH of 7 is a neutral solution, equal concentrations of hydrogen ions and their basic counterpart hydroxy ions. ... The H in pH stands for hydrogen.
What does P in pH mean?
pH. The H stood for 'hydrogen ion' and the p for '
puissance' (French), 'Potenz' (German) or 'power'
What is the pH of urine?
Normal urine pH is slightly acidic, with usual values of
6.0 to 7.5, but the normal range is 4.5 to 8.0. A urine pH of 8.5 or 9.0 is often indicative of a urea-splitting organism, such as Proteus, Klebsiella, or Ureaplasma urealyticum.
What is the pH of milk?
6.5 to 6.7
The pH of milk at 25C, normally varies within a relatively narrow range of
6.5 to 6.7.
What pH is pure water?
Pure water has a pH of
7 and is considered “neutral” because it has neither acidic nor basic qualities.
What is the principle of pH?
6. 6 Principle pH is defined as
the negative logarithm of hydrogen ion concentration. pH= -log [ H+ ] p = power H = hydrogen [H+ ] = hydrogen ion concentration The pH of a solution can be measured by the pH meter.
What pH is safe to drink?
The U.S. Environmental Protection Agency recommends that the pH level of water sources should be at a pH measurement level between 6.5 to 8.5 on a scale that ranges from 0 to 14. The best pH of drinking water sits right in the
middle at a 7.
Is 9.5 pH water good?
If water is below 7 on the pH scale, it's "acidic." If it's higher than 7, it's "alkaline." EPA guidelines state that the pH of tap water should be
between 6.5 and 8.5.
How do you balance the pH in your body?
Use the following tips to decrease acidity in your body, reduce risk of diseases and optimize health.- Reduce or Eliminate harmful acidic foods from your diet. Sugar. ...
- Choose healthier acidic foods. ...
- Increase alkaline foods to 70% of your diet. ...
- Incorporate alkalizing lifestyle choices.

What happens if your pH is too high?
If the pH gets higher than 7.8,
the water is becoming too alkaline. When water is too alkaline, it reduces the effectiveness of the chlorine — the pool chemical that kills pathogens. Water with a pH that's too high also can cause skin rashes, cloudy water and scaling on pool equipment.
Why is urine pH high?
A high urine pH may be due to:
Kidneys that do not properly remove acids (kidney tubular acidosis, also known as renal tubular acidosis) Kidney failure. Stomach pumping (gastric suction)
