What does P in pH stand for?
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 V V mean?
volume percentConcentration: Volume/Volume % When the solute is a liquid sometimes it is convenient to express its concentration in volume/volume percent (v/v %). The definition of v/v % is. Wine has about 12 mL of alcohol (ethanol) per 100 mL of solution.
What is the symbol of K?
Potassium’s symbol, K, comes from kalium, the Latin word for potash.
Is pH above 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.
Why is P in pH lower case?
Answer 4: “pH” stands for “power of hydrogen”, and the atomic symbol for hydrogen is H. … The p is not capitalized because it is not an element, and capitalizing it would indicate that we were talking about phosphorous, for which P is the elemental symbol.
What’s the difference between AR and MR chemistry?
In biochemistry this unit is called the dalton, with symbol Da, although the name and symbol have not been approved by CGPM. (6) For molecules Mr is the relative molecular mass or molecular weight; for atoms Mr is the relative atomic mass or atomic weight and the symbol Ar may be used.
What is the element name for P?
PhosphorusPhosphorus is a chemical element with symbol P and atomic number 15.
What is the name for Br?
Bromine is a chemical element with symbol Br and atomic number 35.
What does P mean chemistry?
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth.
What does P stand for on the periodic table?

Does P mean negative log?
The p-scale is a negative logarithmic scale. It allows numbers with very small units of magnitude (for instance, the concentration of H+ in solution) to be converted into more convenient numbers, often within the the range of -2 – 14.
Why is potassium’s symbol K?
The name derives from the English “potash” or “pot ashes” because it is found in caustic potash (KOH). The symbol K derives from the Latin kalium via the Arabic qali for alkali. It was first isolated by the British chemist Humphry Davy in 1807 from electrolysis of potash (KOH).
Why is iron called Fe?
The name derives from the Anglo-Saxon iron of unknown origin. The element has been known from prehistoric times. The symbol Fe is derived from the Latin ferrum for “firmness”.
Is vitamin K a potassium?
Vitamin K is a vitamin that aids in blood clotting. Vitamin K sometimes gets confused with Potassium. Potassium is a mineral. The human body produces some Vitamin K.
What is the name of Li+?
Lithium ionLithium ion | Li+ – PubChem.
What does HG stand for on the periodic table?
The symbol Hg that mercury is known by comes from its Greek name, hydrargyrum, which means “liquid silver” — to reflect its shiny surface. The element is also known as quicksilver for its mobility.
What does V stand for in chemistry?
VanadiumVanadium is a chemical element with the symbol V and atomic number 23.
What is the name for ca2+?
Calcium ionPlease visit the Calcium element page for information specific to the chemical element of the periodic table. Description: Calcium(2+), also known as ca(2+) or calcium ion, belongs to the class of inorganic compounds known as homogeneous alkaline earth metal compounds.
