What is p used for?
p is a letter it is used to spell words. If there was no p we would be going to _izzeria to eat _izza and that just doesn't sound a_ _etizing.
Why NaOH is used as stop solution to determine specific activity of alkaline phosphatase?
This serves two functions; first, it stops the enzyme-catalyzed reaction by changing the pH to one unsuitable for the enzyme (the enzyme is denatured at high pH and so unable to function). Second, it deprotonates the p-nitrophenol to give the yellow colored p-nitrophenylate.
What is p in pH?
pH is the scientific abbreviation for power of Hydrogen.p=power H=hydrogen. The "p" in pH comes from the notation of the probability of finding a Mole of H+ ions in a given amount of solution which is written as P(H+)=Moles of H+ per litre. Unfortunately the Probability expressed in numbers is not the ideal way to describe and compare things. The best way to do this is to have a scale and have everything fit between its extreemes. Thus the pH scale was devised where the negative log of the concentration of H+ ions gives a scale from 0 to 14. This does not mean that the definition of "p" in "pH" changed but it only says that the old name (probability of H+) is now being used to refer to the the "pH scale".
What is the abbreviation of PH?
pH is the negative logarithm of the activity of the hydrogen ion in a water solution; it is used to evaluate the acidity/alkalinity of a solution.The letter H is the symbol of hydrogen; p is very probable from power.
What does pH indicator?
p = -log H= concentration of hydrogen in solution (H+) therefore, pH= -log [H+] or [H+] = 10-pH
What do the initials pH stand for?
The concept of pH was first introduced by Danish chemist S L P Sorensen in 1909. pH is claimed to have come from pondus hydrogenii, potentia hydrogeni (Latin) potentiel hydrogene (French) and potential of hydrogen (English). it stand for POTENTIAL HYDROGEN.

What does the acronym pH?
The H means hydrogen, but noone save the inventor of the pH system truly knows what the p means.
Why is there a big H in pH?
The "H" stands for hydrogen, just like the "OH" in pOH refers to the ion hydroxide. The first letter of all atomic symbols is capitalized. Perhaps an obvious follow-up question might be, "Why is there a small p in pH?". I would suspect this is so that people did not think the P stood for phosphorus.
