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".The optimal pH range for Pseudomonas aeruginosa is around 6.6-7.4. However, P. aeruginosa is known for its ability to adapt and survive in a wide range of acidic and alkaline environments.
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.
Measuring m alkalinity helps determine the buffering capacity of water and the ability to resist changes in pH. p alkalinity is used to calculate the amount of acid needed to lower the pH of water. Both measurements are important in understanding and managing water quality in aquatic environments.
There exist three species of alkalinity; bicarbonate, carbonate and hydroxide. The concentration of each species will vary with pH. Total alkalinity is the measurement of all species of alkalinity in the water. The concentration of each of the three species can be determined by titrating a water sample with acid of a known concentration and using chemical indicators, phenolphthalein (P indicator),methyl orange (M indicator), or a pH meter to determine "endpoints". The chemical indicators change color at a certain pH points(the endpoint). The mix of alkaline species change as pH decreases. Hydroxide alkalinity disappears below pH 10.3, carbonate below 8.3 and bicarbonate below 4.3 (or thereabout). The P indicator turns from pink to clear at or below pH 8.3 The M indicator turns from orange to yellow below pH 4.3. The amount of acid required to produce a color change is used to calculate the amount of P and M alkalinity. The P and M results are use to calculate "O" or hydroxide alkalinity. Depending on the ionic constituents of the water, these relationships can change or be interfered with.
The partition coefficient of paracetamol is reported to be around 0.36 at pH 7.4.

p = -log H= concentration of hydrogen in solution (H+) therefore, pH= -log [H+] or [H+] = 10-pH

The correct notation is pH, with a lowercase 'p' and an uppercase 'H'. It is used to measure the acidity or alkalinity of a solution on a scale of 0-14.

p is very pobably from power and H is Hydrogen
7 Pillars of Wisdom
Phthisic is pronounced tiz-ik so the ph and the second h are silent.
The color change range for p-naphtholbenzein indicator is usually pH 3.8 - 6.0. Below pH 3.8, the indicator is colorless, and above pH 6.0, it turns purple.
It comes from the German word "Potenz" meaning power or potential.
If you think about it really hard, pH doesn't quite make the F sound, but it's own unique sound very similar to F. Speak out loud: The P sound followed by the H sound. Keep going faster: "P---H, P--H, P-H, PH, until the two letters are closely heard next to each other. This is when you should understand why PH makes the F sound and how the letter H makes the letter P sound so much different when placed right after it. You can do the same thing with SH, TH, LK, etc. just think about it out loud.
