Who named pH?
King Philip II
The Philippines are named after King Philip II (1527-1598) of Spain. The country was discovered by the Portuguese navigator Ferdinand Magellan in 1521 (while in Spanish service). Later tension arose between Portugal and Spain and in 1542 Spain re-claimed the islands for themselves, naming them after its then king.
What is pH full form?

What is the pH of urine?
Urine has the highest range of pH compared to other bodily fluids. The American Association for Clinical Chemistry says the normal urine pH range is between 4.5 and 8. Any pH higher than 8 is basic or alkaline, and any under 6 is acidic.
Can pH be negative?
Summary of Negative pH
Negative pH is possible and simple to calculated, but not something you can easily measure. Special electrodes are used to assess extremely low pH values. In addition to negative pH, it’s also possible for pH to have a value of 0.

What is the pH 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 of lemon juice?
between 2 and 3
Because they contain a high amount of citric acid, lemons have an acidic pH. Lemon juice has a pH between 2 and 3, which means it’s 10,000–100,000 times more acidic than water (1, 2, 3). A food’s pH is a measure of its acidity. The pH of lemon juice falls between 2 and 3, meaning it is acidic.
What is the pH of stomach acid?
The normal volume of the stomach fluid is 20 to 100 mL and the pH is acidic (1.5 to 3.5). These numbers are converted to actual acid production in units of milliequivalents per hour (mEq/hr) in some cases. Note: Normal value ranges may vary slightly depending on the lab doing the test.
What is Urobilinogen urine?
What is a urobilinogen in urine test? A urobilinogen in urine test measures the amount of urobilinogen in a urine sample. Urobilinogen is formed from the reduction of bilirubin. Bilirubin is a yellowish substance found in your liver that helps break down red blood cells. Normal urine contains some urobilinogen.
Why is my pee cloudy?
What causes cloudy urine? The most common cause of cloudy urine is the presence of alkaline. Urine is comprised of water, salts and waste from the kidneys and the balance of these components affects the alkaline or acidity (pH) in urine. Normal urine acidic-to-alkaline levels range from 4.5 to 8 pH.
What does a pH of 7.5 mean?
A quick introduction to the pH scale
The right pH levels are needed for good health. The pH scale ranges from 0 to 14. The readings are based around a pH of 7, which is neutral, like pure water: A pH below 7 is acidic. A pH higher than 7 is alkaline or basic.
Is pH more than 14 possible?
It describes how many hydrogen ions (protons) are present in a solution: the higher the pH, the lower the hydrogen ion concentration, and vice versa. But the scale does not have fixed limits, so it is indeed possible to have a pH above 14 or below zero.
