Where did the word pH originate?
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.
Why is it called pH?
The Carlsberg Foundation itself says pH means “power of hydrogen”. However, German chemists claim it stands for Potenz (also meaning power), whereas the French say it is their word for power, puissance.
What is the meaning pH?
pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
Who gives the term pH?
The concept of pH was first introduced by the Danish chemist Søren Peder Lauritz Sørensen at the Carlsberg Laboratory in 1909 and revised to the modern pH in 1924 to accommodate definitions and measurements in terms of electrochemical cells.
Why is pH pronounced V?
7 Answers. The source of Stephen is the Greek name Stephanos. This name was borrowed into English long enough ago that the intervocalic [f] sound was voiced to become [v]. This is a regular sound change that was also responsible for some other f~v alternations in English, such as loaf~loaves.
Why pH is not more than 14?
One far end is not more than 1M of hydrogen ions, which results in a pH value of not more than 0. While on the other end is not more than 1M of hydroxide ions which results in a pH value of not more than 14. The pH value goes out of the 0-14 range when the concentration of the solution exceeds 1M.
What does P mean in pH?
pH. The H stood for ‘hydrogen ion’ and the p for ‘puissance’ (French), ‘Potenz’ (German) or ‘power’
Is PH always pronounced as F?
Most of the time, PH is pronounced like an F , not as two separate sounds. However, there are exceptions to this rule. You’ll also find out how PH became part of the English language.

Where does the word pH come from in science?
Which is the correct formula for the element pH?
pH = -log [H+] where log is the base-10 logarithm and [H +] stands for the hydrogen ion concentration in units of moles per liter solution. The term “pH” comes from the German word “potenz,” which means “power,” combined with H, the element symbol for hydrogen, so pH is an abbreviation for “power of hydrogen.”
Who was the first person to describe pH?
Answer: pH is the negative log of hydrogen ion concentration in a water-based solution. The term “pH” was first described by Danish biochemist Søren Peter Lauritz Sørensen in 1909.
What does pH stand for on the pH scale?
Here is the answer to the question and a look at the history of the pH scale. pH stands for “power of hydrogen.”. The “H” is capitalized because it is the hydrogen element symbol. pH is a measure of how acidic or basic an aqueous solution is. It is calculated as the negative logarithm of hydrogen ion concentration.

Why is the H capitalized in the abbreviation pH?
The H is capitalized because it is standard to capitalize element symbols. The abbreviation also works in French, with pouvoir hydrogentranslating as “the power of hydrogen”. Logarithmic Scale The pH scaleis a logarithmic scale that usually runs from 1 to 14.
