What does pH stand for in pH balance?
potential hydrogen
pH may look like it belongs on the periodic table of elements, but it’s actually a unit of measurement. The abbreviation pH stands for potential hydrogen, and it tells us how much hydrogen is in liquids—and how active the hydrogen ion is.
What is negative pH?
A negative pH occurs when the molarity of hydrogen ions in a strong acid is greater than 1 N (Normality). You can calculate a negative pH when an acid solution yields a concentration of hydrogen ions with molarity greater than 1. For example, the pH of 12M HCl (hydrochloric acid) is calculated like this: pH = -log[H+]
Which pH level is good for health?
7.35 to 7.45
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].
Who found pH value?
Søren Sørensen
In 1909 Sørensen, a Danish chemist, introduced the concept of pH as a convenient way of expressing acidity.
What is the pH of apple juice?
3.48-3.69
pH of Selected Foods

What is the highest possible pH?
The pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.
What is the pH value of milk?
about 6.7 to 6.9
Milk — pasteurized, canned, or dry — is an acid-forming food. Its pH level is below neutral at about 6.7 to 6.9. This is because it contains lactic acid. Remember, though, that the exact pH level is less important than whether it’s acid-forming or alkaline-forming.
What is the pH level of grape juice?
between 3.0 and 4.0
The pH of grape juice is generally between 3.0 and 4.0, varying in this range depending upon the metabolic activities of yeast and the other microbes present.
What is the pH of fruit juices?
between 2.0 and 4.5
Fruit juices usually have low pH values that range between 2.0 and 4.5 due to the presence of organic acids that vary within the different type of juices.
What pH is apple juice?
What is the pH of orange juice?
Orange juice, which generally has a pH around 3.5, is acidic because it contains citric acid. Citric acid is a weak acid which means that it does not completely dissociate in water. The behavior of weak acids can be described by an equilibrium constant, Ka.
What is the pH of this orange juice?
Undiluted orange juice (UD) = pH 3.9, orange juice: distilled water diluted (1:4) = pH 4.0, and NaOH neutralized= pH 7.0.
What is the pH level of fruit juice?
Fruit Juice pH Levels. Apples, oranges, grapes and cranberries are all moderately acidic. Cranberry juice is the most acidic, with an approximate pH value of 2.3 to 2.5.
What is the pH value of cranberry juice?
Cranberry juice is the most acidic, with an approximate pH value of 2.3 to 2.5. Grape juice has a pH of 3.3; apple juice has an approximate pH value of between 3.35 and 4; the pH of orange juice ranges from 3.3 to 4.2. Dental Health and pH Levels
Is it better to drink the juice or eat the fruit?
Although they are natural sugars, they have the same effects as refined sugars in soda and other sweetened beverages. It’s better to eat fresh, whole fruit than drink the juice, because the sugars are less concentrated. Also, fruit is rich in fiber, which helps mediate the effects of sugars on blood glucose.
